Ok, so, one of my biggest suggestions to anyone using any kind of technology is to LEARN YOUR KEYBOARD SHORTCUTS! While it may not seem like much to save half a second or two instead of moving the mouse through some menus, these fractions of time can add up! And you have a precious few prep minutes to begin with, this may make all the difference.
Many programs use the same shortcuts – and I’m not just talking about your basic Ctrl-Z to undo. The more you learn these the more they will become part of the way you interact with the computer and the more you will begin to use these powerful machines to their full potential.
