Could someone please update the reference section on all the Editing tools: Slip, Roll, Ripple etc., as there is a lot of functionality hidden in them that's just not mentioned.
Various combinations of SHIFT, CTRL and ALT with the various tools can duplicate clip, create gaps, insert clips from elsewhere on the timeline where there are no gaps and some other interesting stuff. Occasionally confusing, but mostly useful.
BTW, is it a strictly necessarily restriction to not being able to change the length of a transition unless in 'Selection Tool (v)' mode?
You can still put the transition on a clip, you just can't alter it while in one of the other modes.
