Hope this will help.
Only for Windows: it's not shortcut but kind of it :)
To Enter/Exit Full screen mode
1. Alt + V (will access Menu -> View) 2. Arrow Up ^3. EnterUPDATE: Looks like the same keys work on Ubuntu too :)
It's easy. Press ctrl+alt+s or open File > Settings > Keymap and open Keymaps select box the default one. Below the select box, type full screen in the search box and right click on the result to set your shortcut. That's it.
