As a kid, I learned to type on a German keyboard1?. And even though my mom tried to make me use a "learn how to type with ten fingers" program I never did. My hands have their very own muscle memory about how to type. I found out that I use the index fingers most to reach many characters, while my hands are moving over the keyboard.
Now, here's the kicker (no flame intended!): I use and used emacs a lot and I've never really had an issue with the way I type, or at least it never felt too awkward. From time to time I like to explore VIM (and other editors) to see what has changed and which features are the new and hot features.
I came to the conclusion that, while my fingers /rest close/ to the home row, my hands move a lot and the default keyboard command layout in vim seems to prefere the fingers resting on the home row with little movement of the hands.
I don't consider myself to be a slow touch typist, but could a formal touch type education increase speed and accuracy? Furthermore is this a Emacs / VIM thing?
UPDATE: I headed over to http://typeracer.com/ :)
1: These days I type on US keyboards while switching between different layouts as needed.
Yes, you're a keyboard worker, learn to use a keyboard properly. No, it's not an Emacs / Vim thing.
If you are using emacs, makeing Caps_Lock another Ctrl key will ease strain on your little finger, when your hands are "locked" in the home row position.

You don't need a formal education, but a lot of discipline, concentration, dedication and hard work will make you a touch typist in a few months.
Touch typing will greatly assist you in your life, if you plan to work with computers as your day job.
Force yourself to move your hands as little as possible and use all of your fingers all of your time.
Rest your left fingers on ASDF, your right fingers on HJKL and start typing. While typing, optimize your reach for every key pressed.
If you plan to be a computer professional, touch typing should be a rite of passage, although it isn't required. But just imagine what would it look like if a master pianist didn't know all keys on piano by heart?
Not really. Especially if you are going to alt-tab to google/read documentation a lot.
Touch typing as it is good only if you are not going to use mouse and F1-F12 which is never true in modern environment.
If you are going to use them, you'll eventaually switch to some form of mutant of touch-typing.
(also whoever thouGHT that typing H with riGHT hand is briGHT idea should be shot in THe face. Left hand do it more naturally in huge amount of cases)
I'd say don't worry about it. You're not a secretary or someone who is having to take down dictated speech. It's far more important for a programmer to spend more time thinking about what they're writing rather than how they write it. If speed of typing is your biggest concern over how productive you are I think you're probably productive enough.
Do you really care? If you do, use the editor that you are more comfortable with. If are you looking for alternative, use M-x viper or learn other emacs extensions that helps you type faster.

I am a vim user (not a beginner not advanced). I use the arrow keys.
I have repeatedly read that it is highly recommended to use the h,j,k,l keys for increased productivity.
I have tried to use them but I can not see how they help in being more productive.
Because if I am to use the h,j,k,l keys to move up/down/right/left I need to press the ESC first to exit the insert mode.
But that defeats the purpose doesn't it? Since the original idea is that you don't need to move your fingers away.
If I am to press ESC I might as well be using the arrow keys and save a keystroke.
Perhaps I am doing something wrong here?
Old terminal keyboards like the ADM-3A terminal didn't have arrow keys.
The keyboard layout looked like this and it already had the arrows for hjkl. (By the way, also note the relation between ~ and Home key)
I think it is mainly for historical reasons that vim still uses it (and many are used to it). Perhaps also because many sysadmins are nostalgic about stuff from the 70/80's, and because they can brag about how they can type faster (like typing is the cause of slow coding...).
The distinguishing feature of vi / Vim is that it's mode-based. That means:
you only stay in insert mode for short bursts of typing
in the other modes (mostly normal mode), you have all key [combinations] available for powerful editing commands (which are highly regular in Vim, and can be combined to great effect)
So, it's crucial that you can switch modes easily. For many users, that means remapping the Esc key to a more convenient location (replacing Caps Lock or Ctrl). Then, using H J K L for navigation (note those are only the basics, and it's often better to use more specific motions like w or f{char}) is quicker, because your fingers can stay on the home row (assuming you're a touch typist, which you should invest in if you spend considerable time with a computer). The cursor keys are located so far off that switching there takes too much time (using the mouse is even worse), and isn't good for your wrists, neither.
The problem with the arrows is not that they are too far: the problem is that they only allow you to move character-by-character and line-by-line. And guess what? That is exactly what hjkl do. The only benefit of hjkl over the arrows is that it saves that slight movement of the arm to and from the arrows. Whether you think that benefit is worth the trouble is your call. In my opinion, it isn't.
hjkl are only marginally better than the arrows while Vim's more advanced motions, bBeEwWfFtT,;/?^$ and so on, offer a huge advantage over the arrows and hjkl.
FWIW, I use the arrows for small movements, in normal and insert mode, and the advanced motions above for larger motions.
mouse-using sucker everyone laughs at: (move)↓↓↓↓↓↓↓↓↓↓→→→→→(move)
hjkl-obsessed hipster: jjjjjjjjjjlllll
efficient vimmer: /fo<CR>
h, j, k, and l are on the home row. If you move your hand to use the arrow keys, you have to readjust when you're done with the arrow keys. This is only a problem for touch typists (which everyone back in the day was).
If you like using the arrow keys, by all means, use them. There is one advantage I see over hjkl: arrow keys work in insert mode. Others prefer to move their fingers only minimally. That's a good argument if you are a touch typist and need to type lots of text. At least for me, my thinking is always slower than my editing, so typing speed and minimal finger movement are not so much an issue to me.
In the end, it's a pretty subjective matter. Use what works for you but try to look around and extend your horizon now and then.
h j k l are a stepping stone to more powerful features. Do you really think that left, right, up, down is as advanced as moving the cursor gets in the 21st Century (or 1976)?
Please note that arrow keys are not recorded while using "q" macros, and bring a lot of sheanigans when you are using some esoteric options because arrows interrupt them. The idea with vim is to end up using composable actions as often as possible and arrows are not.
Besides it doesn't make much of a difference anyway. I had the same strule as a kid switching arrows for WASD, once you get used to it it's just another way, closer to where your hand already is.
And it's not just vim, you would not believe how convenient it is to go the extra mile and learn the terminal shortcuts for movement, copy-paste, history, etc. My laptop's arrows broke last year and I couldn't find the time to solve the issue (Amazon reach the space, but not the island where I live). It was a blessing. Now I rarely use arrows anymore, because ctrl-p/ctrl-n/ctrl-b/ctrl-f/etc. it's just more ergonomic. I just lay my hands on top of the keyboard and don't move them anymore. Ironically now the fartest I move my hands from standard position is to press ESC, wich happens quite often in vim.
A few times I've heard "wait, your terminal/editor can do what!?" when doing fancy things with public. Probably their toolset can do it too, but they haven't go the extra mile of truly learning them. Trust me, it's worthwhile to do so. These tools have been designed this way for a reason.
I recently broke my finger and can now only type with my right hand. This has seriously impacted my typing speed. Since I write software for a living, this is a serious problem.
I have been doing some research, but haven't found a great solution yet. Here's what I've come up with:
Wacom tablet + hand writing recognition software. Is it possible to write code with hand writing recognition software?
one handed keyboards -- I have only found expensive (> $100) keyboards. These look like they have a steep learning curve.
one handed typing instructions: http://www.aboutonehandtyping.com/manualcompare.html. Does this really work?
What do the one handed coders out there use?
If you're a two-hand touch typist, the answer is a "mirrored" layout.
Mirroring lets you begin touch-typing with one hand almost immediately. Pretty crazy how easy it is. Based on the muscle memory you already have.
If you're typing with your right hand:
Type all right-hand keys normally.
Don't type left hand keys. Instead type the same motion (but mirrored) with your right hand.
So if you want to type:
"D" -> type "K" instead.
"W" -> type "O" instead.
"S" -> type "L" instead.
Same row of keyboard, same finger, same motion. Your muscle memory can already do this... kind of like how you're unable to pat your head and rub your belly at the same time. The wires in your brain are crossing somewhere.
Software to mirror the keyboard as described above:
Hold Spacebar to mirror:
Linux - MirrorBoard
Mac - Mirror-QWERTY
Windows - AutoHotkey version of Half-QWERTY Half-Keyboard
Predictive Text; Automatic Mirroring
Mac - One-Hand Keyboard
Windows - One-Hand Keyboard
Regarding one-handed keyboards, I've tried using a frogpad and found it ok for typing text, but unusable for coding. The symbols require several consecutive key presses and I found it impossible to use shortcuts reliably. It was too easy to hit the wrong key and get it stuck in the wrong mode.
Nobody has mentioned ENTI-key aka Coffee++ Layout yet? It is exactly designed for programming with one hand (left). And unlike qwerty, it is even optimized for speed and ergonomics. I used it some years ago for a short while and I don't know if it still works on newer systems. I think I used it for writing CSS: Typing the words with left, typing all those numbers on the numpad with right.
I can not recommend pen+handwriting. I usually use a tablet PC and handwriting code is terrible. I tried it on Windows 8 and Linux with Cellwriter, and both are not bad programs, but I still switch to onscreen keyboard whenever I can. But maybe the problem is my scratchy writing :)
I also can tell from experience that learning a new layout is not as complicated as it sounds. Especially if the layout is more logical than qwerty. I use Neo Layout since 10 years and getting the hang of it went smoothly, I was able to write a blog article after an evening of training.
"But what if you have to use qwerty on another PC?" This, also, is no problem, really. My simple trick is to never look at the keyboard when using Neo, but glimpse at it when qwerty-ing.
Good luck to anyone who wants to or has to use one hand for typing!
Now, the time to heal a broken finger will be shorter than it takes to adapt to one handed coding, not to mention the time it takes afterwards to get back to two-handed coding
Also, the time it takes to learn the methods is time you could've spend on coding (read: making a living).
Knowing this, we need a quick-fix, short term solution.
First of all, A good IDE, with code completion and similar functionality will help you a lot.
Secondly, use the shortcuts of the IDE, remember, there are Shift, Altand Ctrl keys on both sides of your keyboard.
(you might want to create a cheatsheet for those shortcuts)
In addition to helping you during your time with your injury, learning the shortcuts will also improve your coding speed when you're back up again.
Now, my comments on your proposals:
Don't, simply, Don't, it'll take even more time to fix writos (typos) beacause recognition will be flaky.
That learing curve will slow you down even more.
Won't even comment on that one...
Mirrorboard
A friend of mine broke his wrist snowboarding, and he had reasonable luck using speech recognition software (Nuance Dragon Naturally Speaking). It worked quite well for email and documentation, which would solve a part of your problem.
Another colleague, Nils Klarlund of AT&T, developed a version of emacs hooked into speech recognition. He even had a home-brewed set of foot pedals for doing shift, control, etc. He used this exclusively for years (due to bad carpal tunnel syndrome).
And maybe your feet can take up some of the burden. This is part of a parallel discussion going on in this question.
And off-topic, but extremely interesting, T.V. Raman, who's been blind since the age of 14, wrote a version of emacs that works with keyboard input and audio output. There's a chapter on it in Beautiful Code. I've seen him use it, and it's completely awesome. And of course emacs is a great interface for more than just text editing.
If you anticipate that your left hand will be out of commission for a long while, and if it's worthwhile for you to learn a new layout, then there exist one-handed Dvorak layouts.
There's some information at PC Guide: Single-Handed Dvorak Alphanumeric Layouts.
There also once was software for Qwerty Half Keyboards that used the space bar as an extra shift key that reversed the keyboard.
Good luck with your injury!
We have a developer in the office that lost mobility in his right hand and probably won't gain back full use of it. He has mainly learned to type well with his left hand and kind of fill in for his right hand. Although he lets his right hand kind of peck for things. He has gained enough speed back for it not to affect his day too greatly from what i can tell.
Only thing i can think of that might let you speed up some while typing with one hand and maybe being able to get a key or two with the other hand might be to use an IDE instead of text editor if you already don't, so you can use tab completion. Kind of a lame solution if you don't like IDEs or just don't have that option in your work environment but might help out a bit.
The same thing happened to me (I destroyed my left pinky). At the time, I didn't touch type, so my only use for my pinky was left-control, left-shift, and caps-lock.
This sounds as if it just happened to you. I promise you'll quickly learn to compensate. Remember, it's quality, not speed, that counts most.
Perhaps you should seize the opportunity and read to improve yourself as a programmer. Or spend some time debugging.
The lack of uniformity of the pgup print screen arrows etc is getting on my nerves. I am wondering if any of the laser keyboards would make me a more efficient keyboarder by allowing me to adjust those keys and make fewer mistakes in programs, emails, and administrative tasks.
I think you are stating that you'd like to go from a physical keyboard to a laser keyboard to improve your typing skills. As well, the only laser keyboard I have experience with had an odd layout that completley lacked the "pgup print screen arrows etc" which you complained about being non-standard, as well as having keys squished into a trapezoid.
I believe you will find it impossible to touch type on a laser keyboard. Typing requires tactile feedback to know where your fingers are at all times.
A better solution to your problem is probably to pick a standard keyboard layout and use it everywhere you can. Personally, I use upwards of four different keyboard daily, but they are all almost the same. My pet peeve with keyboards is the location of the \ key which tends to move around.
I like to use vi-style keybindings, so I wouldn't miss the keys outside of the main "block" of keys on a standard 101 keyboard.
I'm not sure what a laser keyboard is, but the Ergodex DX1 lets you move the keys around. Very useful for some things, but I doubt that typing would be one of them.
I believe that if you're planning to use that a lot, if you don't have a "good touch/feeling" keyboard, you will have problems mostly with your hands... Ergonomacy is very important specially if your working lots of hours in front of your computer. Have you imagined what it is like introducing 5000 words in a day without having the smooth and pleasing feature of the keys suspension!? imagine typing 5000 words all day long knocking your fingertips all day long in a wooden table. That's got to hurt!
I'm considering switching to a Dvorak-based keyboard layout, but one optimized for programming (mostly) Java and python (e.g. DDvorak, Programmer Dvorak, etc.). What particular keyboard would be best for such an undertaking? I'd consider either natural or straight keyboards.
Thanks.
I strongly discourage you from learning a layout that has been heavily optomized for any one programming language (or even a class of them..) it's much, much easier to change languages than keylayouts, and you'll have a lot of trouble finding the tweaked layouts on any random computers you need to use.
That said, I've used dvorak for years (something like 7-8 years now) on a Kinesis Contoured keyboard and it works wonderfully. The kinesis is programmable, switches between qwerty/dvorak, and you can remap the keys all you want (so you could try out ddvorak or programmer dvorak pretty easily, without making software changes, if you wanted).
The contoured keyboard also forces you to touch-type more "correctly", since you can't easily reach across the keyboard with the wrong hand.
Typematrix
(source: typematrix.com)
Plain vanilla dvorak is best imho. Yes, it does move 3 or 4 keys such as {}: etc out of the way, but you quickly get used to them in the new position, and after a while it makes no odds at all.
The pay off comes in being able to use any random pc - flick the keyboard layout to standard dvorak (which is on just about all PC's, unlike most obscure programmer layouts), and away you go. If you're used to a non-standard dvorak layout, and are forced to use a normal dvorak layout on a qwerty labeled keyboard, I suspect you're in for a whole ton of backspaces (and curse words).
I've only been using dvorak for a few years, but I can't imagine programming using anything else. (Especially with vim, the dvorak layout seems to end up with lots of the keys in much handier positions =)
oh, and as mentioned above - kinesis contoured keyboard is the way to go if you're considering changing layouts for R.S.I issues.
I think the ErgoDox is probably the best option. You used to have to order the components and build it yourself, but now you can purchase it assembled. Here is what it looks like when completed:
I think the ErgoDox is the best option. Apparently the DataHand also supports Dvorak, but I think it would have a pretty steep learning curve:
The components for the ErgoDox typically run about $250 when all is said and done, although it can definitely be built for less than that. I think the DataHand costs around $800.
Any 'normal' keyboard should be pretty much adequate for dvorak, including simple ergonomic (split in equal halves) keyboards. Some of the more esoteric split-ergonomic keyboards that aren't equally split may cause problems with the way that dvorak weights the finger usage though.
If you're going to learn dvorak, I would personally avoid plain dvorak, as it moves punctuation commonly used in programming, such as parenthesis, brackets, braces, etc too far away from the hands: There are a number of 'programmer dvorak' implementations out there which adjust dvorak for this 'oversight'.
I started this post in reply to Tom's post but it grew slightly long.
I learned to touch type at the same time as switching to the Dvorak layout and found that using a qwerty keyboard helped a lot. It stopped me from being tempted to look down at the keyboard. There's no reason to need the labels if your going to touch type and learning to touch type is more important than changing to dvorak.
Right now I'm using the Programmers Dvorak layout that I've made slight modifications to and find it easier than qwerty was.
I recently found out about the Developer's Dvorak but think it's too different for me to learn while still being able to use normal dvorak. It changes the vowel placement and just about half the other keys.
If you are planning on using a custom keyboard layout that's very far from the norm it's good to have something like Portable Keyboard Layout that you can put in a portable drive to use on any [windows] computer.
Do you use a natural keyboard, or a straight one? Keyboard preference can be intensely personal, but many higher-end keyboards have keys fitted specifically for the location of the key (slant and curvature), meaning for Dvorak you'll need to ignore the labels, move the keys and eliminate that advantage, or go with something like the blank das keyboard
My BROTHER of keyboard land. I think I found the holy grail in terms of programming keyboards. Behold the keyboard that retains the layout within the keyboard. I have a custom Dvorak keyboard layout not particularly for programing, mostly for essay writing. I do program a lot though. That retains programmable macros within its brain. That has 24 function buttons. And that has mechanical switches (if it had cherry blue or buckling it would be perfect, it currently sports alps, which arent bad at all). It is based on the renowned Northgate omnikey.
CVT Avanat Stella

On the other hand, you could go 150 bucks under with the IBM Workstation, its legendary buckling spring design is a holy grail among typists. And its 24+ function buttons should prove useful. Plus its vintage goodness is something any geek would adore.
Although switching a keyboard format through software is an easy fix, having a keyboard like the Typematrix helps alot. I've been using the Typematrix 2030 for 4 years now and own 2 boards. One is for work and the other is for home use. I can now use any keyboard I want but the typematrix is definitely more comfortable and timely. This keyboard comes with software that will aid you in learning Dvorak if you don’t know how to type yet.
I switched to the dvorak keyboard layout about a year ago. I now use dvorak full-time at work and at home.
Recently, I went on vacation to Peru and found myself in quite a conundrum. Internet cafes were qwerty-only (and Spanish qwerty, at that). I was stuck with a hunt-and-peck routine that grew old fairly quickly.
That said, is it possible to be "fluent" in both qwerty and dvorak at the same time? If not, are there any good solutions to the situation I found myself in?
I've never used a public computer, but carry a keyboard and(/or, if you are good enough) just change the settings on the machine.
There's a special place in hell for people that change keyboard mappings on public computers.
Web
For your situation of being at a public computer that you cannot switch the keyboard layout on, you can go to this website:
http://www.dvzine.org/type/DVconverter.html
Use this to translate your typing and then use copy paste. I found this very useful when I was out of the country and had to write a bunch of emails at public computers.
USB Drive
Put this Dvorak Utility on your USB drive.
Run this app and it will put a icon in the system tray on windows. This icon will switch the computer between the two keyboard layouts and it works. (If you have tried switching back and forth from dvorak to qwerty you will know what I mean. Windows does the worst job of this one bit of functionality.)
Very possible. Although I became sadly mono-keyboarded after learning Dvorak, my wife is equally speedy at both. She recommends learning the other layout slowly, with frequent breaks to reacquaint with the previous layout.
DVAssist on a USB stick should make it easy to switch layouts on random computers. I
Yes, it is very possible. Just remember to use Qwerty every once in a while. I've been leaning Dvorak myself for about 2 weeks, and I'm up to 75wpm average. I use Qwerty every day for a bit, but most of the time I'm using Dvorak. My Qwerty speed is still averaging around 100wpm.
I also learnt the Korean Dubeolshik layout several years ago, and I average about 100wpm on that too.
Learning different keyboard layouts is much easier than learning multiple languages. And people still manage to remember their native tongue! So if you ever knew Qwerty, with a good bit of practice you should be able to get back up to speed on that fairly quickly.
That said, is it possible to be "fluent" in both qwerty and dvorak at the same time? If not, are there any good solutions to the situation I found myself in?
I've switched to Dvorak a few years ago and I've been fluent in qwerty and dvorak most of the time since (only slightly slower in qwerty than I used to be; much faster than I used to be when I use dvorak instead).
I found that the only part where switching back and forth was really hard was the beginning: I needed a few months until dvorak felt natural enough so that switching back and forth wouldn't confuse me (and hurt the learning curve). After a few months, switching back and forth was a little awkward, but quickly became entirely natural after I got used to it (school computers and a few games didn't easily let me change to dvorak, so it was nice to be able to work either way). So I think if you practice this a bit, it should be fine :)
Incidentally, once I was comfortable with both layouts, learning other layouts was extremely easy in comparison to learning dvorak. It took me only a few hours until I felt more comfortable typing Japanese characters (Hiragana direct input) than I did spelling them out, even though I had to learn it by hitting all keys and seeing what produced which character. It felt a bit like it did with languages -- once you knew two well, learning other similar languages is a lot easier than it was for the second :)
FWIW, I did finally find solution to the situation. I had my travel buddy (who is still stuck in the qwerty stone age) type while I dictated. That was a 10x speed improvement over my hunting-and-pecking. And much easier, too.
I'm ambidkeyboardwhatever, but in two different languages, so that helps with the muscle memory that someone mentioned. I use a Qwerty in English and Azerty in French. My colleagues curse every time they try to use my computer!
I looked briefly at learning Dvorak, but that would only be able to replace Qwerty, because it doesn't have the accented characters.
Having said all that, whatever keyboard layout you choose, the most important thing is to learn to touch-type!
Myself, I type 40wpm Dvorak versus 80wpm QWERTY, which roughly correlates with how often I use these layouts. It takes me about a minute of typing to fully make the switchover.
My sister has managed to train herself to type QWERTY on full-size keyboards but Dvorak on the miniature keyboard on her ASUS Eee, and has no trouble switching between two keyboards at will. She does have major problems when trying to use Dvorak on a full-size keyboard or QWERTY on the Eee, so I guess it's something related to muscle memory.
So, with some qualifications, I'd say that yes, it is completely possible to be "ambikeyboardrous".
Yes, it's completely possible to be fluent in both Dvorak and Qwerty, but you have to specifically work at it to develop the dual fluency. When I began to learn Dvorak it initially crippled me in Qwerty, so I wasn't able to type easily in either layout. But I was dealing with carpal tunnel and unable to do much typing anyway, so learning Dvorak couldn't make me any slower. After several months of switching between Dvorak and Qwerty increasingly often, the switch got easier and easier every time.
Now I can switch instantly. It's like there's a keyboard layout mode switch in my subconscious. I can't see it, but I can tell my brain what layout I want to use, and my fingers do the rest.
But if you're interested in learning Dvorak, consider whether it's worth the effort:
If you're interested in Dvorak to improve your typing speed, my advice is not to get your hopes up. It takes a long time to learn and I'm not convinced it improves typing speed. And it makes basic key shortcuts like those for cut/copy/paste a lot more annoying.
If you're interested in Dvorak because it seems like a cool ability or would look good on a CV, don't bother. Learning a foreign language is far more interesting.
If you're interested in Dvorak to reduce hand pain, give it a go. I'm not sure if it reduced my hand pain or not, but I can believe that it would, because it definitely reduces the distance one's fingers have to travel.
I've been typing Dvorak for about 10 yearns now. I find that I can switch back to qwerty pretty fluently after a few min. I have to look at the keyboard at first but, it comes back. What's funny is that I can only switch back to Qwerty if I'm using a computer or keyboard thats not mine. If I switch the mode to Qwerty on my own laptop, I just struggle. It has to be in Dvorak. =)
Yes. I type Dvorak on a Kinesis Advantage keyboard on my desktops, but type qwerty on my Macbook. Possibly it helps that they are so different, my muscles figure out what it is that they are typing on.
I would say no. I have used both, and they are different for very good reason (warning, history lesson)
The Dvorak keyboard is optimal, the qwerty layout was designed so that the pegs on a typewrier would not collide (so letters that often come next to each other are split up)
Because these are so different, its really not possible to be really good on both. You will find that even if you look at the keyboard while typing you eventually develop muscle memory that allows you to know where the keys are. This will get ALL messed up if you start moving where the keys are.
#Thomas Owens - the person in that cafe after you is going to be proper befuddled :-D
I guess to be good on both you'd have to alternate all the time. I have enough trouble switching between my laptop and desktop keyboards :-)
I'm using a homemade version of QWERTY (with all french letters mapped) at home and at work. I am personally stuck when I have to use the usual layout here (AZERTY). I feel your pain.
For what I have witnessed, everyone gets used to a single mapping, and trying to use an other layout is quite hard.
I've never used a public computer, but carry a keyboard and(/or, if you are good enough) just change the settings on the machine.
