/print command macro.

/run SlashCmdList["S"] = function(a) print (a); end 
/run SLASH_S1 = "/print"

Small shortcut so you don't need to type "/run print(x)" each time. Throw it into a macro and press it once per reload and get a /print command that will print out whatever text you want. It won't let you print variables though, so it's kind of limited in it's current state.
