If, and I do mean if, you happen to have someone sighted around who uses a
computer, the fastest way to determine whether selection is somehow broken
is to have them take a look while you're doing it.  What shows up on the
screen as a result of "selection by keyboard" is indistinguishable to what
shows up for either "swipe over" text selection or point and click mouse
selection.

I see no point in anyone doing independent troubleshooting that can, and
sometimes does, take hours if you happen to have someone you can call over
to "take a quick look" and have an instant answer.

I know that not every reader here has that luxury, but those that do should
not view asking for a "quick check" as dependence, but efficiency and
"working smarter, not harder."
