How to disable global menu activation in Ubuntu 16.04 Unity by Alt?

Question

ubuntu

how to make this menu displayed (activated) only when hovering the mouse cursor?

I ran into this problem because some software has useful key combinations like Alt + f, and if there is an item in the global application menu that starts with f (for example, file, as in the screenshot above), then the Alt + f combination does not work, but unnecessary activation works the files item of the global menu, how can I disable it?
