Hold the L key to temporarily turn off/on ripple edit - Often I am doing a lot of ripple edits and I want to make a change that will screw up the whole timeline. It would be great to just hold the L key and drag stuff around and then release the L key when done leaving ripple edits still on. CTRL+L is still a great toggle, but temporary on off would save a ton.
Hold the U key to temporarily ungroup clips - Often I want to have audio continue running after I cut the video for a clip. I ungroup the clip and drag the edges where I want. Then I re-group the clip by selecting both audio and video and pressing G so that I can move around the clip. Being able to just hold the U key to make the adjustment and then when done releasing the key leaving the clip grouped would save a ton of clicks.
