Oh yes.

Better still: select variables from the main window via shift-click, 
ctrl-click or whatever, then right-click and choose "make this a list"

I like this: however, there's a syntax problem; not unsolvable, but a bit 
annoying. At present, modtest has one optional argument (a scalar), mainly 
used in a time-series context. Allowing for a list makes syntax parsing a 
bit more complex. But then, a nice opportunity opens: how about replacing 
"add" and "omit" with "modtest <list> --add" and "modtest <list> --omit", 
respctively? Clearly, this would be massively backward-incompatible, so 
obviously it would be a 2.0 thing; still, in the meantime we could keep 
the two.
