Formats glitch, doesn't happen all tthe time - suspect it has something to do with VL switching
Configure Tag Browser (Ctrl+5) sometimes opens the drop down and gives it keyboard focus, but only immediately after opening the Tag Browser - I think.
Find Next (Ctrl+2) opens an empty find box and gives it kb focus, but I would have thought that's what Find in Tag Browser (Ctrl+1) should do, and Find Next should only do anything if the Find box has been opened and there's something shown in it.
'Click' found item and Collapse All seem to work as they should.
There's no way to close the Find Box, maybe Collapse all could do that.
