AudioTrack's poset is on p317 of the manual. I noticed an additional mention of exclamation point on p318 of the manual.

It says there that the mark is a convention "to indicate that it is an intelligent guitar style" when using "Guitar Macros". That covers things like chord voicing, walking bass and strum patterns.
