Just found out:
- You can set the start point of a symbol in the properties inspector
- There's a "convert to symbol" hotkey
- You can hold enter to play the timeline and release it to stop, instead of pressing twice
- You can click and drag to select frames on the timeline instead of shift-clicking
Also found out:
- CS4 bugs are just as annoying in 2018 as they were in 2009
That CC subscription is looking damn good right now.
