By default, the cut/copy/paste short-cuts in GVim on Ubuntu are:

 Cut    "+x
 Copy   "+y
 Paste  "+gP

I would like to use control key combos in GVim, like I use in Firefox and othe gnome applications. How do I configure GVim to work like other Gnome apps?

I would think you can add this with the :imap command (tried it just with Ctrl+X in Windows which worked, pressing ctrl+c seems to cancel the command though so you might have to do it in vimrc).

:imap <C-X> "+x
:imap <C-C> "+y 
:imap <C-V> "+gP

If you add it to your ~/.vimrc you just need to remove the : in front of imap.

imap only adds the bindings in insert mode, so you might want to change it to just map or something else. Look into :help mapmode to learn more about remapping and unmapping stuff.

Good luck!

Add the following lines to your _vimrc or .vimrc

source $VIMRUNTIME/mswin.vim
behave mswin

But beware, visual mode is then CTRL-Q instead of CTRL-V.

For an overview what mswin.vim does see the mswin.vim sourcode. It is commented very well and if some command is unclear you can easily look it up in vim's help.

Here is a quick overview compiled from the source:

backspace and cursor keys wrap to previous/next line CTRL-X and SHIFT-Del are Cut CTRL-C and CTRL-Insert are Copy CTRL-V and SHIFT-Insert are Paste Use CTRL-Q to do what CTRL-V used to do Use CTRL-S for saving, also in Insert mode CTRL-Z is Undo; not in cmdline though CTRL-Y is Redo (although not repeat); not in cmdline though Alt-Space is System menu CTRL-A is Select all CTRL-Tab is Next window CTRL-F4 is Close window

At Nippysaurus' request: I put following in my .gvimrc to show Ctrl-V besides Paste in the menu:

unmenu! Edit.Paste
aunmenu Edit.Paste
nnoremenu 20.360 &Edit.&Paste<Tab>Ctrl-V        "+gP
cnoremenu    &Edit.&Paste<Tab>Ctrl-V        <C-R>+

I didn't test it thoroughly, just a quick check if it did what I expected. Works for me, hope it works for you;-)

If you want to maintain the normal vim behavior but also allow for less cumbersome use of the system clipboard, see Accessing the system clipboard. If you would like gvim to use the system clipboard as its default buffer (so any x, y, p, etc. command uses the clipboard) then add the following line to your vimrc:

set clipboard=unnamed

I personally use the buffers far more within vim than between vim and the system; so I'd rather have a slightly more cumbersome shortcut than have my system clipboard constantly clobbered. But it's nice that the option is there for those who would prefer it.

If you want Cut/Copy/Paste to work using the "standard" hotkeys, but you don't want to change any of the other configuration options in gvim, try do add the following to ~/.vimrc.

vmap <C-c> "+yi
vmap <C-x> "+c
vmap <C-v> c<ESC>"+p
imap <C-v> <C-r><C-o>+

Paste only works in Visual and insert mode, so you don't have to worry about the conflict with Ctrl-V and blockwise Visual Mode. This isn't a problem, because Copy and Cut put you into insert mode, so you can immediately paste afterwards. If you try it out you'll find that it feels completely natural.

I came up with this configuration after several iterations of tweaking, and I think it's "perfect" now. If you're even a little bit dissatisfied with your current copy/paste configuration, try this out and I bet you'll love it.
