Just wondering if there is a list of keyboard shortcuts for idoceo. I do some tasks several times a day, e.g., Seating Plans/Tools/Rearrange/Randomize plan - keep positions, and they would be easier if I could initiate them from the keyboard.

Hello Pauhana658,
If you hold the Command ⌘ you will see the configured shortcuts on screens that allow them.
You won't see any in the seating plan, but here is what you should see in the gradebook view
