the mtPaint documentation says you can setup Icewm for the PrintScrn key to take a screenshot by adding this line to /root/.icewm/keys
key "Print" mtpaint -s
this does not seem to work for Puppy
i typed xmodmap -pke | grep 111, which showed this result:
keycode 111 = Multi_key
i added this line to /root/.icewm/keys and restarted Icewm
key "Multi_key" mtpaint -s
this seems to work ... pressing the PrintScrn key now takes a screenshot (i use the US keymap)
