Does the HUD work?

Question

linux

In recent days I have been trying to use the vaunted HUD . I enter specific words - does not offer a single option.
I think I want a lot. I try something simple like Copy, Paste - it offers all sorts of garbage from the system menu.
I think the program is probably not connected to the HUD system. I try to call copypaste in the console, gedit - the same picture.
I think, probably, it is necessary to write in the language of localization. Well, you get the idea. No effect.
