Quick navigation tip from an Adobe developer: You can navigate the animation timeline by keyboard if you set up a shortcut.

Go to Edit>Keyboard Shorcuts (Alt+Ctrl+Shift+K) to bring up the Keyboard Shortcuts and Menus dialog:

Guess what: you can’t use PgUp and PgDn as the shortcuts. The most intuitive pair of keys I could get it to accept were Ctrl+* and Ctrl+/ on the numeric keypad. I then mapped these two keys to my ShuttlePro’s jog dial.

Were they really expecting users to use the mouse every time they want to advance frame? The writer jokingly says “please request this as a feature for next release“. Maybe they should have consulted the After Effects team?
