Have you ever wanted to use the CapsLock key or your mouse's Button 5 as additional modifiers? Modified Modifier (ModMod) allows you to do just that! There are still limitations - since Ctrl, Alt and Shift are still the only officially supported modifiers in the game, you cannot use your ModMod modifier in macros for example.
Read up on how it works and download it to add to your keybinds by visiting the addon's page here.
Are you the author of a mod that you think belongs in this spotlight? Just upload/update it to WoWInterface, and it will automatically be considered for that week's Pick.
"You'd be surprised how many people violate this simple principle every day of their lives and try to fit square pegs into round holes, ignoring the clear reality that Things Are As They Are." -Benjamin Hoff, The Tao of Pooh
