well, a mouseless editing is a very fast way to make rough cuts or to do what i call ” cleaning the rushes” if you digitized a whole tape and you need to choose ur useful shots and organize them into different sequences for faster access later … your standard keyboard shortcuts are enough to switch between browser canvas and timeline , to open sequences and bins,control the patch bay in your sequence,choose the tools,choose clip from the browser,zooming,navigating on the sequence,adding or removing in/out point and marks and even making an edit to tape ,etc…
but when it comes to trimming,fine tuning , using effects or keyframes,using any of the tools, there is no escape but to use the mouse …
