Does F9 not work on a Mac?
Screenshot and Image posting guide might be helpful.
When I made this
map of ships, I really wanted to use a separate color for all the level 18 phantoms in the Hinterseas. If ship spawn points move in this next release, I'll have 1-10, 11-15, 16-20, 21-25, 26-30, 31-35, 36+ for my next map. (Hmmmm. Black, purple, blue, green, yellow, orange, red. Yup, that works...but will cause a lot more overlapping.)
