cavalier889, thanks for responding. I read a few posts back, you're very busy!
The thing that confused me; assigning a single key-stroke for 2 commands, 'Man the AA guns', and 'Fire at Long-Range.
It works fine, but the crew first states, 'Fire at Long Range', then to 'Man the AA guns'.
I can't reverse the crew-orders, (Man AA guns 1st, then Fire Long-Range 2nd), but it doesn't matter because the command works fine.
The other confusing thing was to assign multiple key-commands ('Edit map' / Map-1, Map-2, 3, etc.). I figured why bother with this, since my custom commands were already assigned to single key-commands. Then it finally clicked!
For instance, I had (or made) single key-maps for 'return to course', 'full down-periscope', 'surface the boat' and 'weather report'. To combine all commands to a new keystroke, -that's- when I needed to add some redundant keystrokes, using the 'Edit Map' Map-1, Map-2 option. It's a very nice feature.
I see there's 286 commands available, and only 181 are mapped. Time to look around for more keys and shortcut commands.
This is a very slick and well thought-out program. Did you create Setkeys on your own? If you're still in school, it might be a really good idea to pursue a career in custom coding/programming applications.
(When in school, I probably spent too much time picking my nose, and staring at girls!

)
Thanks again.
p.s. does anyone know if there's a Command Name to display the 'Battery-Oxegen-Co2' screen? If not I'll try one of the slide-out mods.
