Current iteration of the add markers pop-up is as follows...
Bring up Exc.
Type "a m c"
Type the name of my marker
ARROW KEY DOWN
ARROW KEY DOWN
ARROW KEY DOWN
ARROW KEY DOWN
ARROW KEY DOWN
until I get to the marker color my choice.
Would love to be able to just like tab or something and then start typing the first letter of the marker, which would then filter the list down so I could just type "c" and then enter to make a cyan marker. Make sense? Currently no way to select colors without arrowing down, which is too many keystrokes. 🙂
