LiteMount allows you to enter two different custom macros that, if enabled, it will use:

1. when you try to mount but it cannot find a usable mount; and
2. when you are in combat, overriding the default combat actions.

On the Macro : Unavailable options sub-panel you can enter macro commands that LiteMount will use out of combat when it can't find a usable mount. That might be because you are in a non-mountable location, or you are moving and don't know any instant-cast mounts.

On the Macro : Combat options sub-panel you can enter and enable/disable macro commands that LiteMount will use in combat instead of its default combat actions. Clicking the "Default" button will copy the macro commands from the default actions for you to modify (note that the default actions may depend on your class).

The macro settings are always per-character and cannot be shared account-wide.
