How could I use MS PowerPoints's virtual laser pointer without having to hold the CTRL key? When I'm doing a presentation I'm not near my keyboard, it would be great if I could show the virtual pointer.
The below only applies to PowerPoint 2013:
It's not very slick, but you can right-click your presentation while prsenting, and from the pop-up menu choose Pointer Options > Laser Pointer. Press ESC to go back to normal pointer.
If you haven't already set it up to use CTRL, another keyboard alternative is to press CTRL L during the presentation, though I know you were after a non-keyboard solution.
