Please describe the problem:
If a tablet computer enters presentation mode, it can only leave by rebooting the machine because there are no pointer/stylus/touch methods offered for escaping the presentation.

Steps to reproduce:
1. Open document
2. Select presentation mode from view menu.
3. Try to escape without a keyboard


Actual results:
You are trapped in presentation mode.

Expected results:
I would expect a button in one of the screen corners which became visible on hover, labelled [End Presentation], which returned the application to normal mode when pressed.

Does this happen every time?
Yes.

Other information:
An onscreen keyboard would allow a tablet to escape, but presentation mode covers my onscreen keyboard.
