I've tried and failed to find the option to change the font bartender uses for keybinds and macro text, and was wondering if someone can point me in the right direction.
It uses one of the 4 default WoW fonts. You can "change" these via font replacement. Google for "wow font replace" to find directions, or search through these forums, instructions have been given here multiple times, as well as many times on the WoWAce and WoWInterface forums.
