Binder is a keybinds profile manager that stores per-character keybinding profiles, allowing you to restore the bindings specifically set for a given character automatically when logging in as that character.

If a profile exists for a given character, as soon as you log into that character, it will load up its profile and restore all of the keybindings associated with it.

If you've never yet logged in to a given character with Binder installed, it will simply create a profile for it with the same bindings as the previous character you played.

If you want to verify that Binder is properly functioning, open the Key Mapping window - the title text should include an indicator of the currently active profile, along the lines of "Key Mapping (Profile: ______)".

NOTE: if you use a localized client and have character names with non-ascii characters in them, Binder might always load a profile called "default" instead of a character-specific one. You can make this "default" profiled saved per-character, however, by following the instructions in the Addon FAQ sticky in this forum to turn on WAR's save_settings_per_character option.
