+1 for being able to release keyboard using shortcut.

A few months back I started working on this exact problem (and made it 
exactly nowhere).  There is already a key combination which can be 
defined for releasing grab, but it doesn't work in client mode.

It would be very useful for these tasks which I constantly am 
inconvenienced by when using remote-viewer.  Citrix has a "local escape" 
key which allows the next key to be passed through. Default ctrl-f2.

- play/pause music playing on local computer using multimedia keys
- answer softphone with keyboard shortcut running on local computer

With respect to the screen saver, I think the current behavior is pretty 
ok: local screensaver is inhibited until the exact moment of ungrab 
(e.g. leaving fullscreen and moving the mouse out) and then the local 
screensaver kicks in.
