If you liked cleaning your edit window you’ll LOVE ruling your rulers!

Rulers Rule!

Option+Click a ruler name: Clears the ruler clicked.

Control+Option+Command+Click on a ruler name: Clears all rulers except the one you click on (note: does not clear the ruler that goes with your main counter as this cannot be cleared)

Control+Click on a ruler name: Turns the grid view on and off.

Command+Click on a ruler name: Changes your main counter, grid, and nudge to that timebase. (where applicable)

edit: had a few extraneous “commands” in there
