Can't unset shortcut for "Print" in GUI

[vi]

1. Settings->Application shortcut
2. "Print"
3. Mouse click at "Print"
4. Mouse click at "<X" button
5. Click a button with green tick
   • (BTW icon is displayed correctly for this buttion)
6. Can't set shortcut, it's already used by action 'History'

Actually I wanted to reassign it to "Display completions window" (like in Vim), but have not found "Display completinos" menu item.

About bug: I can't reproduce it, but, I've made changes, which might fix it. Could you please check, if bug is reproduced on master?

About shortcut for completions window: If you think, we need it, could you please open new issue and explain, why it is necessary?

[vi]

Now unsetting a shortcut works.
