Tool addition: paint an entire string with 2 clicks

#tools #HotKeys
Since we can mark a base with Ctrl-click, seems to me we can put Alt-click to work.
RFE: paint an entire string using hot-key combination.

Select first base with Alt-click … base is highlighted by pulsing ring … Alt-click 2nd base paints intervening string.

Yes, I have had times when this would be very nice.
