A4 should have keybindings for every major GUI functionality

[Andrea Colangelo]

Currently we can switch ROIs with arrow keys and [0...9], but we lack keybindings for the following options:
- opening a presentation
- closing a presentation
- going fullscreen (and back windowed)
- switching to editor (and back to player)
- rotating the image {A,}CW

Can we remove this from the 0.3 milestone? I don't think it's really important for this release.

[Andrea Gualano (andrea-gualano)]

Done.
Of course if someone is working on it, feel free to change it back.

[Francesco Marella (francesco-marella)]

I've been added some standard hotkeys to A4. (fullscreen, open/close window, etc)

We could assign:
- Ctrl+E for switching to editor
- Ctrl+R for rotating the image c-w (Shift+Ctrl+R a-c-w)

btw those two functionality should be added to the main menu first.
Comments?

I agree on adding an option to toggle editor mode in the menu. Adding an option to the menu is probably less useful (except, maybe, for options like +/-90° or +/-180°). By the way, I like the keybindings you suggest. Francesco, mind working on this issue?

[Francesco Marella (francesco-marella)]

Ok I will work on this asap.
