How to shortcut formatting text

In composing slides I need to do a number of things very regularly such as: select font color, increase font size a bit, decrease font size. To do this requires lots of clicks and menu navigation. Can I configure fast buttons to:

  1. Change font color to a previously selected one (as in Powerpoint) I need a single button click
  2. Increase/decrease font size at the moment I have to navigate through format->character->fonts and choose a font size. This should really be a single button click.

Can this be done?
