Re:voxmea :: To exit a selection, v or vv should do it (the latter if you are in V, or line-wise visual mode). You're essentially twiddling the visual mode and insert/command modes separately.
Also, I just noticed after this build upgrade (but possibly changed one or two before) that I don't get a right-click menu on anything in the side bar. Specifically, I commonly used the "open containing folder" semantic. Was this a configuration change I could set back, or is it cooked in?
