Somewhere or another I read that I could put

set mouse

in my .gnuplot file in order to be able to use the mouse for zooming.
Then I discovered/read that 'a' (that is, the 'a' key) restored the
plot to it's full size (the right mouse button only zooms in, not out,
AFAIK) and that 'g' toggles a grid.
