I use the mouse, but in a fast way. What I use in Premiere Pro is:
- I have a shortcuts assigned to the f1, f2 and f3 (f1 is undo, f2 is delete, f3 is cut or add edit).
- I have activated the "Select follows playhead"
And with the mouse I move the playhead through the timeline and, when I consider is something I need or don't, I cut and delete the unwanted video, letting just the images I need.
The F1 shortcut was the last one I made. This was for never take off my hand of that part of the keyboard.
