I know that I can use ctrl+w to shift between different Vim windows. But how do I remap the CMD-key to replace ctrl+w in various way? I'm specifically looking to bind cmd with the arrow keys, so that I can shift to NERDTree easily with CMD+LeftArrow. Appreciate the assistance.
I've tried to add the following to $MYVIMRC...
nmap <silent> <D-h> :wincmd h<CR> // For going to NERDTree
nmap <silent> <D-l> :wincmd l<CR> // For going back to file I'm working on.
In the left-hand side of a mapping, Command+Left is written <D-Left>. With this and other issues fixed (see below), your mappings should look like this:
nnoremap <D-Left> <Cmd>wincmd h<CR>
nnoremap <D-Right> <Cmd>wincmd l<CR>
or, simply, like this:
nnoremap <D-Left> <C-w>h
nnoremap <D-Right> <C-w>l
Other issues:
Recursive mappings (nmap) should be reserved to the rare situations where you want to use another mapping in your mapping. This is not the case, here, so nnoremap is the best choice.
The mapped commands don't echo anything so <silent> is useless.
Vim's comment leader is ", not //.
You can't have comments on the same line as a mapping anyway, see :help map-comments.
The newish :help <Cmd> is cleaner than using : in the right-hand side of a mapping.
Note that these mappings only work in the MacVim GUI.

I find a .vimrc file config:
" Move selection up/down (add =gv to reindent after move)
:vmap <D-S-Up> :m-2<CR>gv
:vmap <D-S-Down> :m'>+<CR>gv
I know the D-S-Up must be a key, but what is the key?
I type:
:help D-S-Up
nothing happened
:help key-notation tells you the meaning of all those <key> notations.
You can't expect :help D-S-Up to do anything because:
it doesn't follow established patterns like i_ctrl-r,
it is a custom mapping and Vim only provides documentation for its own commands.
<D> is the Cmd key on Mac keyboards, <S> is the Shift key, and <Up> is the Up arrow key.
So <D-S-Up> means Cmd + Shift + Up.
The Cmd key only works in the MacVim GUI.
Non-portable mappings are worthless.
One should use :xmap or :xnoremap for visual mode mappings, not :v*.
Non-recursive mappings should be used by default unless one really wants recursion.
Using someone else's vimrc is a bad idea.
By the way, here are enhanced versions of those mappings:
nnoremap <silent> <D-S-Up> :<C-u>move-2<CR>==
nnoremap <silent> <D-S-Down> :<C-u>move+<CR>==
xnoremap <silent> <D-S-Up> :move-2<CR>gv=gv
xnoremap <silent> <D-S-Down> :move'>+<CR>gv=gv
where:
<silent> prevents the commands in the mapping from echoing useless info,
<C-u> removes any default range inserted by Vim,
move-2<CR> is a more readable version of m-2<CR>,
== re-indents the line,
gv=gv reselects the lines, re-indents them, and re-selects them again.
Have a look at Move entire line up and down in Vim
In an answer you can read (concerning the line :vmap <D-S-Up> :m-2<CR>gv):
According to the shortcuts above, pressing Cmd-Shift-Up/Down will shift the block selection up/down. "D" is the Command key in MacVim, for Windows try "C" (Control), or "A" (Alt) (eg. would be Control Alt f).
Since I don't have a Mac myself, I can't check, but it's most certainly true.
I normally work with more than 5 files at a time. I use buffers to open different files.
I use commands such as :buf file1, :buf file2 etc.
Is there a faster way to move to different files?
What I use:
Go to the previous buffer: :b# or :bp
Go to the next buffer: :bn
If you know your file is loaded in buffer 5: :b5
To get a list of buffers: :buffers or shorter: :ls
And have a short look on :he buffer
And the wiki entry on Easier Buffer Switching on the Vim Wiki: http://vim.wikia.com/wiki/Easier_buffer_switching
SO already has a question regarding yours: How do you prefer to switch between buffers in Vim?
A few mappings can make your life a lot easier.
This one lists your buffers and prompts you for a number:
nnoremap gb :buffers<CR>:buffer<Space>
This one lists your buffers in the "wildmenu". Depends on the 'wildcharm' option as well as 'wildmenu' and 'wildmode':
nnoremap <leader>b :buffer <C-z>
These ones allow you to cycle between all your buffers without much thinking:
nnoremap <PageUp> :bprevious<CR>
nnoremap <PageDown> :bnext<CR>
Also, don't forget <C-^> which allows you to alternate between two buffers.
Below I describe some excerpts from sections of my .vimrc. It includes mapping the leader key, setting wilds tab completion, and finally my buffer nav key choices (all mostly inspired by folks on the interweb, including romainl). Edit: Then I ramble on about my shortcuts for windows and tabs.
" easier default keys {{{1
let mapleader=','
nnoremap <leader>2 :#"<CR>
The leader key is a prefix key for mostly user-defined key commands (some plugins also use it). The default is \, but many people suggest the easier to reach ,.
The second line there is a command to # execute from the " clipboard, in case you'd like to quickly try out various key bindings (without relying on :so %). (My nmeumonic is that Shift-2 is #.)
" wilds {{{1
set wildmenu wildmode=list:full
set wildcharm=<C-z>
set wildignore+=*~ wildignorecase
For built-in completion, wildmenu is probably the part that shows up yellow on your Vim when using tab completion on command-line. wildmode is set to a comma-separated list, each coming up in turn on each tab completion (that is, my list is simply one element, list:full). list shows rows and columns of candidates. full's meaning includes maintaining existence of the wildmenu. wildcharm is the way to include Tab presses in your macros. The *~ is for my use in :edit and :find commands.
" nav keys {{{1
" windows, buffers and tabs {{{2
" buffers {{{3
nnoremap <leader>bb :b <C-z><S-Tab>
nnoremap <leader>bh :ls!<CR>:b<Space>
nnoremap <leader>bw :ls!<CR>:bw<Space>
nnoremap <leader>bt :TSelectBuffer<CR>
nnoremap <leader>be :BufExplorer<CR>
nnoremap <leader>bs :BufExplorerHorizontalSplit<CR>
nnoremap <leader>bv :BufExplorerVerticalSplit<CR>
nnoremap <leader>3 :e#<CR>
nmap <C-n> :bn<cr>
nmap <C-p> :bp<cr>
The ,3 is for switching between the "two" last buffers (Easier to reach than built-in Ctrl-6). Nmeuonic is Shift- 3 is #, and # is the register symbol for last buffer. (See :marks.)
,bh is to select from hidden buffers (!).
,bw is to bwipeout buffers by number or name. For instance, you can wipeout several while looking at the list, with ,bw 1 3 4 8 10 <CR>. Note that wipeout is more destructive than :bdelete. They have their pros and cons. For instance, :bdelete leaves the buffer in the hidden list, while :bwipeout removes global marks (see :help marks, and the description of uppercase marks).
I haven't settled on these keybindings, I would sort of prefer that my ,bb was simply ,b (simply defining while leaving the others defined makes Vim pause to see if you'll enter more).
Those shortcuts for :BufExplorer are actually the defaults for that plugin, but I have it written out so I can change them if I want to start using ,b without a hang.
You didn't ask for this:
If you still find Vim buffers a little awkward to use, try to combine the functionality with tabs and windows (until you get more comfortable?).
" windows {{{3
" window nav
nnoremap <leader>w <C-w>
nnoremap <M-h> <C-w>h
nnoremap <M-j> <C-w>j
nnoremap <M-k> <C-w>k
nnoremap <M-l> <C-w>l
" resize window
nnoremap <C-h> <C-w><
nnoremap <C-j> <C-w>+
nnoremap <C-k> <C-w>-
nnoremap <C-l> <C-w>>
Notice how nice ,w is for a prefix. Also, I reserve Ctrl key for resizing, because Alt (M-) is hard to realize in all environments, and I don't have a better way to resize. I'm fine using ,w to switch windows.
" tabs {{{3
nnoremap <leader>t :tab
nnoremap <M-n> :tabn<cr>
nnoremap <M-p> :tabp<cr>
nnoremap <C-Tab> :tabn<cr>
nnoremap <C-S-Tab> :tabp<cr>
nnoremap tn :tabe<CR>
nnoremap te :tabe<Space><C-z><S-Tab>
nnoremap tf :tabf<Space>
nnoremap tc :tabc<CR>
nnoremap to :tabo<CR>
nnoremap tm :tabm<CR>
nnoremap ts :tabs<CR>
nnoremap th :tabr<CR>
nnoremap tj :tabn<CR>
nnoremap tk :tabp<CR>
nnoremap tl :tabl<CR>
" or, it may make more sense to use
" nnoremap th :tabp<CR>
" nnoremap tj :tabl<CR>
" nnoremap tk :tabr<CR>
" nnoremap tl :tabn<CR>
In summary of my window and tabs keys, I can navigate both of them with Alt, which is actually pretty easy to reach. In other words:
" (modifier) key choice explanation {{{3
"
" KEYS CTRL ALT
" hjkl resize windows switch windows
" np switch buffer switch tab
"
" (resize windows is hard to do otherwise, so we use ctrl which works across
" more environments. i can use ',w' for windowcmds o.w.. alt is comfortable
" enough for fast and gui nav in tabs and windows. we use np for navs that
" are more linear, hjkl for navs that are more planar.)
"
This way, if the Alt is working, you can actually hold it down while you find your "open" buffer pretty quickly, amongst the tabs and windows.
Once the buffers are already open, you can just type :b partial_filename to switch
So if :ls shows that i have my ~./vimrc open, then I can just type :b vimr or :b rc to switch to that buffer
There are many ways to solve. The best is the best that WORKS for YOU. You have lots of fuzzy match plugins that help you navigate. The 2 things that impress me most are
1) CtrlP or Unite's fuzzy buffer search
2) LustyExplorer and/or LustyJuggler
And the simplest :
:map <F5> :ls<CR>:e #
Pressing F5 lists all buffer, just type number.
I've been trying to create a shortcut for switching between open window splits in vim, rather than having to use ctrl+w+[arrowkey] I would prefer to just be able to use ctrl+[arrow keys].
This is what I currently have in my vimrc:
map <silent> <C-v> <c-w>v
map <silent> <C-Left> <c-w>h
map <silent> <C-Down> <c-w>j
map <silent> <C-Up> <c-w>k
map <silent> <C-Right> <c-w>l
The first shortcut for doing the vsplit works fine, however none of the others work. I've tried several variations of this and yet none of them do anything.
I'm using standard debian wheezy with KDE, vim is running from konsole and the only plugins I have installed are NERDTree and Airline.
I'm hoping someone can help provide a solution because I've been searching online for hours and trying hundreds of options and nothing seems to make any difference.
EDIT
verbatim insert for the shortcuts doesn't output anything at all, neither in shell or vim.
First, make sure that <C-Left> is not handled by konsole. Start a fresh one and use cat:
$ cat
^[[1;5D
That is how it should work for <C-Left>. Similar for other arrows. If <C-Left> doesn't work in such a way, search for "\e[1;5D": ... in /etc/inputrc and ~/.inputrc and comment it. You may have to log out and log in to get effect of these changes.
Next, use
:verbose map
in vim to display all mapped shortcuts and their source. You should see your bindings in this list. Your bindings are correct and all work in my case.
try this:
nnoremap <C-DOWN> <C-W><C-J>
nnoremap <C-UP> <C-W><C-K>
nnoremap <C-RIGHT> <C-W><C-L>
nnoremap <C-LEFT> <C-W><C-H>
I want to remap <PageUp> to <C-u> and PageDown to <C-d> per the Vim scrolling documentation.
As it stands right now, my /etc/vim/vimrc looks like this:
nnoremap <PageUp> <C-u>
nnoremap <PageDown> <C-d>
I've tried a lot of different combinations and nothing I've done has worked.
My goal is to make the cursor move to the Start Of File or EOF when holding down PageUp/PageDown. As it is right now, the cursor stops before it gets all the way to the top (and PageDown scrolls past the EOF). Just annoyances I'm trying to fix.
EDIT: The above settings work fine. I was placing my mappings too early in the file.
What about the following mappings?
nnoremap <PageUp> gg
nnoremap <PageDown> G
Or simply using gg and G?
Instead of placing the mappings into the system-wide /etc/vim/vimrc, you should put user customizations into the ~/.vimrc file. Nonetheless, the global configuration (if that's what you want) should work, too. That it doesn't means that the mappings get cleared or redefined. You can check with
:verbose nmap <PageDown>
If it didn't get redefined, you have to hunt for :nunmap commands in all loaded scripts (:scriptnames), or capture a log with vim -V20vimlog.
You can do this with
map <silent> <PageUp> 1000<C-U>
map <silent> <PageDown> 1000<C-D>
imap <silent> <PageUp> <C-O>1000<C-U>
imap <silent> <PageDown> <C-O>1000<C-D>

I am using NERDTree on vim and usually open files with i
Is there an easy way to switch between different panes? Currently I use CTRL+W+W to move from one pane to another.
Long ago I found a tip (once on vim.org, now on wikia, apparently) that I've stuck with. Remap ctrl-[hjkl] to navigate splits. It has served me well.
" Use ctrl-[hjkl] to select the active split!
nmap <silent> <c-k> :wincmd k<CR>
nmap <silent> <c-j> :wincmd j<CR>
nmap <silent> <c-h> :wincmd h<CR>
nmap <silent> <c-l> :wincmd l<CR>
I prefer hitting single keys over hitting key-chords. The following maps pane movement to arrow keys:
" Smart way to move between panes
map <up> <C-w><up>
map <down> <C-w><down>
map <left> <C-w><left>
map <right> <C-w><right>
I know this is an old question, but I have a perfect way. Using the number of the split.
split_number C-w C-w
The panes are numbered from top-left to bottom-right with the first one getting the number 1.
for example to go to split number 3 do this 3 C-w C-w, press Ctrl-w twice.
Key mappings are definitely the way to go. I use the mappings mentioned by overthink. I also include the following mappings in my vimrc to move the splits themselves.
" Move the splits arround!
nmap <silent> <c-s-k> <C-W>k
nmap <silent> <c-s-j> <C-W>j
nmap <silent> <c-s-h> <C-W>h
nmap <silent> <c-s-l> <C-W>l
This makes it so that if the split opens in the wrong spot (lets say the left side and I want it on the right) I go to that split and hit <C-S-l> and the split moves where I want it to.
In order to be consistent with changing tabs via gt & gT, I'm currently trying out the g mappings for changing splits. I tend to hit the shift key as I go for the Ctrl key so this helps me avoid that mistake until I get better at not doing so.
nnoremap gh <C-W><C-H>
nnoremap gj <C-W><C-J>
nnoremap gk <C-W><C-K>
nnoremap gl <C-W><C-L>
I have mapped ctrl+w ctrl+w to <tab> (under normal mode as in normal mode tab does not have any use)and that's have made my life easier as now I can switch between panes easily by pressing <tab>.
For switching to a particular pane, I can press <i> + <tab> to switch between panes as split window panes also got their own number which can replace i.
Ex. i = 1,2...n.
Very easy way of achieving it. Type this shortcut twice, and that should work
ctrl+w ctrl+w
