Guess maybe I should say when I put stuff in so it gets the 'new' post there.
Icons 650-699 in now.
I haven't seen any instruments, which is just lame if you ask me since bards are probably the class that would make the highest number of specialized hotkeys.
You can click on any auto-made key though and figure out what its icon is. Whenever the game gives you a new ability it is just making a hotkey, so you can actually edit any auto key. As example, with my cleric alt I modified the gem hotkey. I added on "Summoning life insurance, and no %td, in the event of my death you can't have my stuff." Always good for a laugh.
On Spring break for a week. These don't take long to do. Maybe 1/2 hour or more per 50 icon set, so I'll try and get a bunch more over the next week. (Particularly since my time runs out on the 10th I think.)
