Hey ze0rb,
- The hotkey is space bar, but can be changed in Keyboard Shorcuts under Editor Preferences
- We have request in our system for reverse play (UE-27539).
- I sent in a feature request for Trim Mode/JKL editing mode (UE-31424).
- Could you expand on the functionality you’d like for trim/splits on mouse clicks? I think I have some idea because I’ve used editing suites in the past, but I just want to confirm what you mean. Possibly with links to Avid or Premiere documentation on the topic.
