I was just about to ask this. I tried it and Textedit does work (i didn't think it would).
I have to say... my minimal coding abilities were no match for those symbols that weren't even on the keyboard.
Looks like I got some learning to do.
EDIT: Okay, that is DEFINITELY not how any coding language is supposed to look like. i think i just opened a weapon's form instead of the coding... Jeez I hate starting out...
