Is there any way to reduce the command in VIM?
In vim to open your NERDTree menu you type :NERDTree, but that actually really annoys me, because it's long and mixed case. Since you close it with q, I want to open it with a short key (maybe :n, you can also provide suggestions for that if you feel like it). How can I change that?
I am sorry if this is simple, but I am a newb, and I don't know form where to start aproaching such a problem -from the plugin files, or is there a special remapping technique in your .vimrc.
You can use
map <F2> :NERDTreeToggle<CR>
to map NERDTree to any key you like (F2 in this example)
it's also possible to map it to :n
map :n :NERDTreeToggle<CR>
but that's not very common, I like using one of the F-Keys because that's faster.

After attempting to use vim a number of times, I'm always been put off by its default key bindings. After some research, I decided to remap the default keys to more sane ones (at least for my tastes). I have a few questions about changing bindings that I could not find answers to through Google.
Is there a way to map a key to an action rather than another key. For example:
:noremap a h
will bind the a key to move the cursor left. Is there something along the lines of
:noremap a move-cursor-left
or
:noremap a :move-cursor-left<Enter>
so I can read my config file afterwards?
Is there a way to unbind all of the default key bindings? I've tried :mapclear but it doesn't seem to work, although it might just be clearing non-default bindings. Unmapping every key manually is not an option. If possible, I would like to export the defaults to a file so I can edit them as I need.
Is there another language I can use to write my own commands for vim other than vim-script? I haven't actually looked into this one so much though. If I can bind an external executable to a command, that would be good enough.
I haven't given up on vim although I would like to ask if there are any vim-like alternatives out there. My Google searches came up with nothing actively developed. If the above cannot be done, or reasonably hacked together, I would like to find a fully configurable, modal, command line text editor that can.
The command set of vi / Vim has 40 years of wisdom encoded into it; completely changing it is a bad idea. I can only repeat the reference to this answer from the comments; that should convince you (to accept this, or choose another editor).
Give the default commands another try. It'll take some time to get used to, but most Vim users swear by these. It's fine to make minor adjustments "for personal style": careful evolution, but not revolution. Also, some people with odd keyboard layouts (like Dvorak or Colemak) swap several keys for convenience.
The move-cursor-left is just h; aided by the excellent :help, you should be able to "read" your remappings just fine.
In general, even though it's possible to write extensions / plugins in integrated languages like Perl, Python, Ruby, etc. (based on support for them compiled into the Vim binary), you won't get around learning some key Vim internals and parts of Vimscript. If you don't feel comfortable at all about this, I'd suggest to use another editor. Unfortunately, with your requirements of full extensibility (and probably broad acceptance and platform support), there's only one serious alternative: Emacs (which cannot only be turned into everything but a kitchen sink, but also into a modal editor, too).
(i know this question is old)
you can reset the binds by just over-writing them
on vim you can use many <things> (idk the name)
e.g.
<Up> = Up-arrow-key
<C-f> = Ctrl, f
<A-Down> = Alt, Down-arrow-key
<Esc> = Escape-key
it's possible to remap the hjkl keys to wasd like this:
nmap w <Up>
nmap a <Left>
nmap s <Down>
nmap d <Right>
I heard that there is no internal function to call when typing a key combo in vim, unlike emacs. So I want to repurpose Ctrl-A to ^ (like, nnoremap < C-A> ^); however, the original function of Ctrl-A is also attractive, so I want to map it to some other keys, say Ctrl-S. How can I do this the vim way?
This question might have been asked but I searched around and did not find anything close. Thanks in advance.
PS: the stupid vim-emacs war is spamming everywhere and nowhere can i find a real solution that makes a desired feature to work in another environment.
The following should do:
nnoremap <C-A> ^
nnoremap <C-A>A <C-A>
This works because the noremap tells vim to do not apply any other mapping, thus the rhs of the second mapping above is the default <Ctrl-A>.
You will notice that the first mapping will take a delay to execute, because vim waits a while to allow you to type the second mapping. Vim-FAQ 20.16 may help if this bothers you.
But I'd advice against changing the default mapping because, as explained here, vim has many default mappings that may seems silly when you start using it. When you understand it better you will have a hard time finding another key to map it or to get used to the old/default mappings.
I have created a keybinding that should indent a whole file.
My first solution looked like this:
map <F4> gg=G
The problem is that after pressing F4, the cursor jumped to the first line of the file. So I have tried to improve my solution with the feature of markers, look like this:
map <F4> mzgg=G'z<CR>
I expected this would have resolved my problem, but the command do the same as the first. When I try to jump to the z marker manually vim told me "marker not set".
After changing the keybinding, I have or course restarted vim! I am using the GVIM 7.3 on a WIN 7 machine.
Thank you in advance for your Help!
Edit:
After trying to get my keybinding working by tipping it directly to vim commandline. I find out that the keybinding was working quite nice. I think problem is that I create a session some times ago (with mksession) and if you load a session I think vim ignores the vimrc-file. Is this assumption right?
Solution:
In these thread I find a soultion to make mksession save less options.
Another lightweight approach: set the ` mark, format the buffer and jump back to the mark afterwards.
:nnoremap <key> m`gg=G``
I would recommend the use of CTRLo and CTRLi which allow to go respectively backward and forward in the jump list. See :help jumps.
The following mapping
map <F4> gg=G2<C-o>
works. (It jumps back two times in the jump list)
But generally, the jump list is a great way to navigate in a file, this is likely the shortcuts that use the most in my daily use. It is also works if you jump to a tag to go back to your original location.
You might also want to use nnoremap rather than map, this way it will only work in normal mode, and you could potentially reuse F4 in combination in another key binding without having recursive mappings.
so
nnoremap <F4> gg=G2<C-o>

Move entire line up and down in Vim
(21 answers)
Closed 9 years ago.
I was wondering which was the shortest way to turn upside down two adjacent lines in vim, for example:
Hi
How are you?
in
How are you?
Hi
Are there some special shortcuts or should I consider to write a macro for this?
Use ddp when your cursor is on the first line.
dd deletes the current line.
p pastes the deleted line under the current one.
What you need is a mapping: what that mapping does, even if it's 20 commands chained, doesn't really matter.
nnoremap <F6> :m-2<CR>==
and
nnoremap <F6> ddp
both do exactly what you want in slightly different ways. One command is complex and relatively smart while the other is simple and relatively dumb but they are equivalent in the way that they are both done with a single keystroke.
Of course you can use somerhing else than F6.
