To me this seems too specialized a use to be worth hard-coding it.

How about using one of the general mechanisms that already exist?

For example:

  PS = 0
  plot "foo" with linespoints pointsize PS

# Now you have a plot on the screen that shows no visible points

  bind "1" "PS=1; replot"
  bind "2" "PS=2; replot"
  bind "0" "PS=0; replot"

# Now you have defined hot-keys to change the size of the points in
# the existing plot.

Or a similar example that uses a hotkey to toggle one plot of many:

  PS1=PS2=PS3=PS4=0
  bind "1" "PS1 = PS1 ? 0 : 1; replot"
  bind "2" "PS2 = PS2 ? 0 : 1; replot"
  bind "3" "PS3 = PS3 ? 0 : 1; replot"
  bind "4" "PS4 = PS4 ? 0 : 1; replot"

  plot FILE1 with lp ps PS1, FILE2 with lp ps PS2, FILE3 with lp ps PS3
