Description:
I use the "mouse as pen" feature a lot in lectures, and I would love to see a possibility to somehow change the color of the "ink" without the need to navigate the popup menu of the presentation.

Steps to Reproduce:
Start a presentation with "mouse as pen" enabled.

Actual Results:
To change the ink color, I need to right-click on the presentation (seems not to be possible on the presenter's screen, I need to go to the "actual" presentation screen) and select "Change Color..." and then select from a Color Dialog.

Expected Results:
It would be nice to be able to either:
- select a color on the presenter console, but I actually dislike writing on the console (it's small on a 14" screen)
- have a keyboard shortcut available (I admit finding one is difficult), but maybe [Ctrl]-[Alt]-[1...4] for a set of 4 predefined colors, or just [R] for red and [G] for something else would be nice.


Reproducible: Always
