Yeah I got what you meant about syntax highlighting (I assume you're probably talking as much about the script editor as I was). I'd like to see syntax highlighting in mIRC's script editor too, but in addition to the traditional highlighting (commands, identifiers, variables) I'd like to see the control codes highlighted differently. I don't mean highlighted based on what kind of formatting effect they have on the text but just highlighting the actual control code characters themselves so that it's easy to see whether you're looking at [Ctrl+K], [Ctrl+B], [Ctrl+R], or [Ctrl+O] instead of the current situation where you have to copy the character and go out of the editor to a mIRC editbox to test what it is.

Spelling mistakes, grammatical errors, and stupid comments are intentional.
