Inefficiency in Vim - vim

I consider myself somewhat familiar with Vim,
hate the arrow keys (let alone the mouse),
regularly look up tips and plugins to get the most out of this tool,
use it daily to manage my cloud servers, etc.
However, I always find myself doing the same mistakes probably inherited from the GUI-world:
too often switching to visual mode to see what piece of code I'm about to manipulate,
undoing changes to retrieve lost statements because I forget to utilize registers (and pasting code on temporary lines just to grab it after other edits),
relying on Ctrl-C & Ctrl-V when working with operating system's clipboard,
keep pressing j button to browse through lengthy files to find certain functions.
Probably my Hungarian keyboard layout prevents me from being faster as most of the special characters (/, [, etc.) are only available as a key combination (with Shift or Alt Gr).
Given this specific situation, what pieces of advice could you give me? Have you faced similar bad habits when you were a Vim-novice? I'd like to see my productivity skyrocket (who wouldn't?). Thanks in advance.

I've found a simple, effective strategy. Choose one action, one task or one set of keys that you think is unnecessarily slow. Figure out a better way of doing this using the vim manual or googling or a plugin etc. Force yourself to use this every time. Rinse, and repeat. The path to efficiency is one-by-one elimination of the slow parts.
I'd also recommend just reading the vim manual from time to time - even if you don't remember everything, knowing something's out there is very helpful.

This probably applies well beyond vim, but
something that worked for me was finding a specific feature that I knew would
be more efficient and concentrate on using that for a week or two.
Just one feature at a time, and possibly using it excessively.
After a couple of weeks it becomes automatic and you can move on to the
next thing.
I learn programming tricks the same way. eg. I'll have a month of using lambda expressions for everything, then a month of mapping and filtering.
(not on production code though)

Probably my Hungarian keyboard layout prevents me from being faster as most of the special > characters (/, [, etc.) are only available as a key combination (with Shift or Alt Gr).
I'm sitting in front of german keyboards all day long and know this problem very well. Some keyboard layouts are simply not very suited for programming / using vim. I think its safe to assume that most programming languages and keyboard shortcuts were designed with the us-layout in mind.
My advice: reset your keyboard layout to us-english and practive touch-typing on that layout (typing without looking at the keys). It won't matter that the keyboard labels are wrong and you'll be much more comfortable using vim hotkeys.
The only problem that still remains for me is to produce language specific characters (german umlauts such as ä,ö,ü) wich i assume will also be a problem for hungarian. For that I use a combination of vim-digraphs, linux window manager digraph-key and windows layout-switching hotkeys.

just keep using it. The more you use it, the better you become at it. VIM isn't too bad. The main thing is you just have to remember that it isn't always in edit mode.

Why are h,j,k,l recommended over using arrow keys for vim?

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.

Is learning ed worth it to boost my speed in VIM?

I've learned the basic/intermediate levels of VIM (it's too vast to list). I often find that I slip back to my old ways and start using the mouse, holding down keys to get somewhere, and doing other stupid things that could be sped up.
Would it be worth spending time to learn ed to break the habits learned from years in a point and click interface? Does using ed cultivate the right type of thinking that will transfer to VIM?
You need a change in habits which is much deeper than simply dropping the mouse. You need to understand that if you really want to learn Vim you have to do it "the hard way": read and memorize text-objects (:help text-objects) operations and movements and try using arrows/hjkl as little as possible.
At first you will be a lot slower, but don't fall back to normal movement. If you need to select a paragraph, use vap, if you need to change the text inside a pair of double quotes use ci" and so on. When these things will come out of your fingers naturally, you'll realize how worth it was the time spent to get used to them.
I learned Vim and became proficient simply by using Vim itself--a lot. I think the key is practice, practice, practice.
If you want to train yourself to avoid the mouse, unplugging it or putting out of reach might help. Learning a whole different program might be overkill, and the knowledge may not translate directly.
Read this post by Bram Moolenaar on the subject of efficient text-editing.
One of the points is that it takes conscious effort to force yourself into the habit of using Vim efficiently.
So yeah, hide the mouse while you're in Vim. And when you catch yourself doing things "the wrong way", stop and do them again correctly. It won't be long before you've learned the proper habits. And has has been suggested: Text Objects. Learn them. Get in the habit of using these and you're 1/2way to being a Vim pro. Using them is addictive; it won't take long.
I think in addition to consciously avoiding the mouse, it also helps to consciously try to force yourself to keep your fingers on home row.

One handed coding -- tablet, special keyboard, one-handed typing?

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.

Is it worth swapping Ctrl and Caps Lock for windows users that don't use Emacs

I've been aware of Steve Yegge's advice to swap Ctrl and Caps Lock for a while now, although I don't use Emacs. I've just tried swapping them over as an experiment and I'm finding it difficult to adjust. There are several shortcuts that are second nature to me now and I hadn't realised quite how ingrained they are in how I use the keyboard.
In particular, I keep going to the old Ctrl key for Ctrl+Z (undo), and for cut, copy & paste operations (Ctrl+ X, C and V). Experimenting with going from the home position to Ctrl+Z I don't know which finger to put on Z, as it feels awkward with either my ring, middle or index finger. Is this something I'll get used to the same way I've got used to the original position and I should just give it time or is this arrangement not suited to windows keyboard shortcuts.
I'd be interested to hear from people who have successfully made the transition as well as those who have tried it and move back, but particularly from people who were doing it on windows.
Will it lead to any improvement in my typing speed or comfort when typing.
Do you have any tips for finger positions or typing training to speed up the transition.
I actually don't swap control and caps and just make caps ANOTHER control key. I can't think of a single time in my life when I have ever hit caps-lock on purpose, so I haven't missed it.
That way, you get used to using it, but if you slip up and use the old control, things still work. It's worked out very well for me.
There's a .reg file to do this here.
I've done it for quite a while now, and it's natural to me, even though I'm not an Emacs user either (I'm in the Vim camp of that particular war :) ). In fact, it's so natural that moving to other machines (coworkers, family members, etc.) causes me grief because Ctrl isn't where it 'ought' to be.
For emacs ctrl should be at caps lock - for vim the escape key should be on the caps lock. I really feel that the caps lock button should be renamed "free parking" and OSes should make a system tray utility to quickly change the free parking button from escape, to control, to anything you need to type over and over again.
I ended up taking the advice in Zach's answer, but I also made Caps Lock behave as an ESC key if it was held and released on it's own using the AutoHotKey script in this gist: CapsLockCtrlEscape.ahk
I also bound Ctrl+Shift+Caps Lock to Caps Lock for the rare occasions when I might need it using this AutoHotKey script:
#IfWinActive
^+Capslock::Capslock ; make CTRL+SHIFT+Caps-Lock the Caps Lock toggle
return
I switched the Caps Lock and Ctrl keys a couple of months ago and after the initial learning period, ~ 1 week, my biggest problem is when I use a computer that hasn't switched the keys.
I first did some registry hack but I can't remember where I found the information on how to do it. Now I'm using a small utility called Remapkey which is included in the Windows Server 2003 Resource Kit Tools even though I think I'm using an older version.
I had no problem making the transition. I use keyboards with both configurations without issue. Perhaps having it as a hardware solution (and the labels properly printed) makes it easier than doing it through software and having to remember how each machine/keyboard is setup.
I think what's best to put on caps depends on your physical keyboard.
At home I type on a Kinesis Ergo Elan where my ctrl keys are under my thumbs, along with 2*alt, space, enter, backspace, delete, pgup, pgdn, home and end; the rest of the keyboard is fairly normally laid out, except the board is split.
With the ctrl keys ready at hand, it really makes the most sense to put escape on caps lock (and caps lock on esc, for the few times I need it). Even if you're an emacser, hey... it doubles as a spare "prefix alt key", and you probably ask your browser to stop what it's doing a few times every day.
On the other hand, if I'm typing on my laptop where the lower left corner key is Fn rather than ctrl (ffs...) and I can't hold down shift+ctrl with one finger, it might make sense to put ctrl on caps (such that I can hold them with a single finger). At least if you're not a vi'er, or you don't mind the escape key being further away (or have some crazy system).
What's really interesting is putting some funky key on shift+shift (yep, both shift keys). This can be done with xmodmap fairly straightforwardly; I put my compose key there. If you don't need compose, you may want to put something else (like, say, esc).
Copy the following code into a file called caps-ctrl-swap.reg, execute the file, agree to allow registry to be changed, log out and back in and your caps-lock and left-ctrl keys will be swapped. I've used this script for whatever version of Windows was current in 2005 and every version in between. I needed it today since Windows 10 updated overnight and it still works great.

Reviews for programmable, tiling window manager ion3

I find the concept of the programmable, tiling, keyboard-focuessed window manager ion3 very appealing, but I think it takes some time to customize it to your needs until you can really evaluate this totally different UI-concept.
Therefore, I would like to read reviews of people who tried it for a longer time as environment for programming (in particular using emacs/gcc).
(The policies of the ion3-author concerning linux-distros are not easy to follow for me, but this should not be the point here...)
I use ion3 daily. It's a wonderful window manager. The tiling interface really enables you maximize real estate. Once you get it setup to your liking, it is much more efficient to navigate via the keyboard. Even moving applications between tiles isn't that hard once you get used to the tag/attach key sequence.
With ion3, Vimperator and the various shells I have open during the day -- I barely use the rodent.
The author's opinions aside -- a good resource for configuring/extending Ion to your liking can be found at:
Configuring and Extending Ion3 with Lua
I've been using Ion daily for nearly two years now. Good things:
Easy to use from the keyboard.
Handles multiple screens (Xinerama) very well (once you have the mod_xinerama plugin), especially as in my case the screens are different sizes.
Very predictable where windows will appear.
Splitting, resizing and moving windows is very easy.
Multiple, independent workspaces on each screen.
Very fast and reliable.
Bad things:
Too many different shortcuts. e.g. there are separate keys for moving to the next tab, next frame, next screen, and next workspace.
Applications that use lots of small windows together work really badly (e.g. the Gimp) because it maximises all of them on top of each other initially.
Sub-dialogs can cause trouble. Sometimes they open in a separate tab when you want them in the same tab, or sometimes the open in the same tab and take the focus when you want to continue interacting with the main window.
These things can probably be changed in the config files, but I haven't got around to it yet. Also, the actual C code is easy to read, and on the few occasions where I've wanted to fix something it has been very easy. I don't feel tempted to go back to a non-tiling WM, anyway.
I've used it off and on for the last few years, I think its a great window manager, but I keep crawling back to kde3 whatever I use.
Its however difficult to put into quantifiable terms why this happens, but its right up there with the gnome-vs-kde battle. Neither side can understand the other.
I would also just love to have kicker + ion3, but they don't gel awfully well.
Moving applications between tiles ( something I tend to do lots ) also is a bit inefficient ( too addicted to the mouse )
( Kicker + Evilwm is a good combination, but evilwm just can't handle stacking in a user-friendly way )
