Emacs 24.5 , CUA mode. Not paste text in the minibuffer

Question

In Windows 7 / Emacs 24.5

1. Copy text e.g. "example" in the kill-ring
2. M-x
3. C-y (yank)
4. Success show text "example" in the minibuffer

But if turn on CUA-mode, the text "example" not yank (paste) by 'C-v' in the minibuffer.

Answer 1

CUA mode makes C-v the yank/paste command.

If you start Emacs with :

emacs -Q

Then turn on CUA mode (M-x cua-mode) you'll see that C-v works as you expect.

Without knowing your setup it's difficult to be sure but it's likely you're using a package which modifies the behavior of M-x (E.g. smex, Ido, ivy, etc.)

It's likely CUA mode won't really have anything to do with this problem. You can verify this by trying to do C-y to yank in the minibuffer too.

Packages which enhance M-x may provide a way to allow you to drop out temporarily, so you can yank text in-place.

Update

From your comments we know you are using Helm, which overrides some bindings in the minibuffer, including C-v which is bound to page down.

Because bindings are applied at different mode (context) scopes, the minibuffer modemap (list of key bindings) will override anything that's applied at a more general context (such as cua mode)

To work around this you'd need to add a binding specifically for cua-paste in the affected mode map. It would need to be applied after Helm has loaded.
