I want pressing backspace to result in:
For references
doing just x or just dl produces
and dh gives
Add the following to your .vimrc:
nnoremap <BS> x
This adds a non-recursive mapping to normal mode, where <BS> now performs x.
If you just want to test this mapping without adding it to your .vimrc, enter command mode with : , type in the line above, then hit enter.
you can map <BS> to do x and then h:
nnoremap <BS> xh
This should be what you are looking for.
update, handle the EOL case:
nnoremap <expr> <BS> col('.')==(col('$')-1)?'x':'xh'

I would like Ctrl-W to allow me to switch windows even when I am in insert mode. How can I make this change?
My motivation is to not need to press escape before shifting windows.
For <c-w><c-j> (as an example), you can do:
inoremap <c-w><c-j> <esc><c-w><c-j>gi
Then you can repeat this kind of mapping for every command you use:
inoremap <c-w><c-k> <esc><c-w><c-k>gi
inoremap <c-w><c-w> <esc><c-w><c-w>gi
inoremap <c-w>+ <esc><c-w>+gi
inoremap <c-w>- <esc><c-w>-gi
...
If you choose this simple solution, then you can finally add this mapping to inhibit the native <c-w> key (= delete the last word):
inoremap <c-w> <nop>
More "smart" solutions could be written, but they would imply a bit more code.
Note 1: as noted in the comments, the mappings to choose depend on which mode you want to reach after the keystroke: the suffix gi in the commands above means that you want to go back to insert mode in the new window; but you can remove this suffix if you want to be in normal mode.
Note 2: the suffix gi could be simply i, depending on the case : see :h i and :h gi
I had the following mapping on my vimrc
nnoremap <TAB> gt
nnoremap <S-TAB> gT
Then I mapped ESC to clear highlights as:
noremap <silent> <ESC> :noh<return>
And then <S-TAB> wont work anymore. If I remove <silent> from <ESC> mapping I see :noh when I press <S-TAB>. I don't know if <S-TAB> and <ESC> has something in common. I'm on Linux, using vim on gnome-terminal.
You're right in assuming that <S-TAB> and <ESC> have something in common. S-TAB is an escape-prefixed keycode.
The ESC keycode is ^[, while S-TAB is ^[[Z. You can see the first part of the S-TAB key code matching the ESC keycode.
See a full table of combinations here.
So you just can't remap the escape key while also remapping one of the key codes including it. Either pick a different key to clear highlights or a different way of switching tabs.
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 use the Vimwiki-Plugin a lot, but remapping <Backspace> and <CR> is just anoying. If I use :nmap, the mapping is shown:
n <CR> #<Plug>VimwikiFollowLink
n <Backspace> #<Plug>VimwikiGoBackLink
If I try to remove tha mapping with :nunmap <CR> I get an "E31: No such mapping" error. Is there a way to give <CR> and <Backspace> its's normal behaviour back?
if you want to just disable it, you could give
:nunmap <buffer> <CR>
because it is a buffer-local mapping.
or
:h vimwiki_<cr>
you found:
<CR> Follow/create wiki link (create target wiki page if
needed).
Maps to |:VimwikiFollowLink|.
To remap: >
:nmap <Leader>wf <Plug>VimwikiFollowLink
if you remap that to another key, e.g. the keys in example <leader>wf, the <cr> would be reset to normal.
because in its code, vimwiki has:
if !hasmapto('<Plug>VimwikiFollowLink')
nmap <silent><buffer> <CR> <Plug>VimwikiFollowLink
endif
same for the <BS>
I'm almost certain that someone else has also had this question, and this may be a repeat, but I'm not sure what to call a command like <C-L> and so I haven't had any luck finding an existing question. If this is a duplicate, please redirect me.
The question arises from a vimrc section that reads like this:
" Map <C-L> (redraw screen) to also turn off search highlighting until the
" next search
nnoremap <C-L> :nohl<CR><C-L>
So what combination of keys do I press (in which mode) to input a <C-L> mapping?
in this line:
nnoremap <C-L> :nohl<CR><C-L>
nnoremap means normal no-recursive map <C-L>... which means, if you press ctrl + l in NORMAL mode, the mapped key-strokes would be applied.
<C-L> means ctrl + l
if you type
:h control
you can see the keycodes:
<C-...> control-key *control* *ctrl* *<C-*
The capital "C" character in <C-L> represents the control key while the capital "L" character represents a "L" character. So pressing Ctrl+L in normal mode should invoke the mapping.
