[vim] Ability to perform a copy

Hi, I’m trying to use the vim mode from CodeMirror and there is one thing bordering me. I’m aware that the command Ctrl-C is used in vim to return to the normal mode, but in a GUI based text editor, Ctrl-C would pretty much always be the copy. I know that most people using vim would want to keep the Ctrl-C to change mode, but I think it could be an option. In the code the Ctrl-C is hardcoded (https://github.com/codemirror/CodeMirror/blob/f1692af532b78b7aeacb9dfc1962e2443866f65b/keymap/vim.js),

if (keyName == 'Esc' || keyName == 'Ctrl-C' || keyName == 'Ctrl-[') {

Wouldn’t be nice to have an option to disable this? What to you think guys? I would be really interested to know your opinion.

I can’t even copy at all. I have to disable Vim mode, copy with CTRL-C and then enable vim mode again.

• Ctrl-C exits insert mode.
• Yanking only places text in the " register. Not possible to paste in other programs.
• Cannot yank to + or * registers as they are not implemented.
• X11 Primary selection does not work either.
• No right-click menu to choose “Copy” from.
• Ctrl-P still works to paste, however. Weird.

This is from using GraphQL Playground, which is using CodeMirror inside an Electron app, on Linux.

IMO yanking to + should perform a normal copy to the system clipboard, no matter what people think about the Ctrl-C situation. That could be a first step.

That sounds like a very reasonable suggestion.
