If your settings Ctrl-c and Ctrl-v in the Vim emulator are handle by Vim you can simply custom your .ideavimrc to use these shortcuts. Here is a simple way to do it, paste this line in your .ideavimrc:
set clipboard+=unnamed
you can refresh the new settings in your IDE without the need to restart the IDE by using the command vim and the path of your .ideavimrc file :
:source ~/.ideavimrc
This method is great, simple and will allow you to use all the editing shortcuts like y, Y, p, P, x to put your code in the clipboard and use it elsewhere on the computer
..
PS : Instead you can also create crazy customized macros for Ctrl-c, Crtl-v in insert, normal or visual mode using the clipboard register by using the quote key " associated with + or * depends and some key editing shortcuts like c,p,y like this :
inoremap <C-v> <Esc>"+Pa
So the behavior is fully customizable (but this is also crazyness)
