R = Rotate (this works)
Shift key with cursor over unit and Drag = Moves units (can't get this to work, I've tried shift-click and drag, shift-right click and drag - no luck)
Delete Key with cursor over unit = Delete Unit (can't get this to work for units - works like a charm for objects)
Fortunately, the unwanted rogue squad got summarily removed by going into the .BAM file itself (thank God it's in plain text!) and it was the last unit I placed so easy to delete that entry, but there's got to be a way within the editor I'm just missing. Right?
Until then, I'm saving after every batch of units (probably a good habit in general
P.S. is there a list of keyboard shortcuts for the editor anywhere? In my attempt to figure out how to delete the rogue squad, I found that "F" = Fixed/Unfixed, X shows a very zoomed out view of the map like on the Briefing/Force Buy screen, the WSAD convention for moving the camera works here, Q and E rotate the map. Up and Down arrows zoom the map (very useful, too).
