How to

How can I use the keypad to move back and forth on the timeline instead of using the mouse pointer?

I already checked the key shortcuts and no mention of it. In my older version I used to be able to move ahead or back by on the keypad in small increments using 2 letters instead of using the mouse. I forgot what they were. Anybody know?

Put the cursor on the track bar and try Ctrl > arrow key left/right
