Ctrl-Y in insert mode is one of Vim's handy extensions that inserts character which is above cursor (see :help i_CTRL-Y). However, sometimes this is not very useful when a user wants to insert many characters. In this case it's better to get a word above the cursor.
Put this in vimrc:
" Wordwise Ctrl-Y in insert mode noremap! <C-Y> <Esc>klyWjpa
You might want to substitute 'W' with 'w', 'E', or 'e'. Try them and choose one that works best for you.
Unfortunately, this simple map doesn't work at the beginning or end of line. Improvements are welcome.
How about a small mod:
noremap! <C-Y> <Esc>klyWjPa
Other interesting variants, depending upon what one wants:
inoremap <C-Y> <Esc>klyiWjPa inoremap <C-Y> <Esc>klyiwjPa
The yiw yanks the "inner word", yiW yanks the "inner WORD". Both of these forms appear to work at both the beginning and end of sentences, with the exception that neither works for a single letter word at the beginning of a sentence.
:imap <F1> <C-O>:set virtualedit=all<CR><C-O>k<C-O>yw<C-O>j<C-O>P<C-O>:set virtualedit=<CR>
is a little bit better, but not really satisfying (a bug in virtualedit/<C-O>?).
Hmm.. I can't get Ctrl-Y to work at all :( I tried :behave xterm but it doesn't seem to do anything for me :(
I found it works in the Linux version, but not in Windows.
- Which version doesn't work for you? I tried using the inoremap <expr> mapping and also using the mapping with the F1 key. Both worked without problems. So be please specific, what mapping did you use, what happened, did you get an error message, etc... Chrisbra 07:22, November 15, 2011 (UTC)
Here is a somewhat elaborate solution that fixes several problems:
- works at the beginning of a line
- terminates at the end of a line (doesn't do anything weird)
- doesn't overwrite the unnamed (last used) register
" wordwise yank from line above inoremap <silent> <C-Y> <C-C>:let @z = @"<CR>mz \:exec 'normal!' (col('.')==1 && col('$')==1 ? 'k' : 'kl')<CR> \:exec (col('.')==col('$')-1 ? 'let @" = @_' : 'normal! yw')<CR> \`zp:let @" = @z<CR>a
What it does:
- Cancel insert mode and save
@z. This macro will overwrite register z and mark z. Use temporary ones that you would never use manually.
- Mark position z.
- Move up, and then move right only if the cursor was not at the beginning of the line on an empty line.
- If the cursor is now at the end of the line, do nothing (and clear
@"so the paste doesn't duplicate the last paste). Otherwise yank to the next word.
- Go back to mark z and paste.
@"and go into insert mode after the pasted text.
You can also change the mapping to yank to the end of a word (change "yw" to "ye" on the third line).
If you have Vim 7 you can use an expression mapping to simplify the mapping. This mapping also will not overwrite any registers or marks
inoremap <expr> <c-y> matchstr(getline(line('.')-1), '\%' . virtcol('.') . 'v\%(\k\+\\|.\)')
