The default Key Bindings menu binds a key to an action bar slot. Clicked binds a key or mouse button to a spell directly, with conditions: on your target, on your mouseover, only in a certain form or stance, only in combat.

Why that helps

Your bindings stop depending on where a spell sits on your bars. Rearrange the bars and every key still casts the same thing. Healers can bind heals to clicks on unit frames, and damage dealers can bind a spell to cast on mouseover without a macro.

A simple start

  1. Open Clicked and add a binding for the spell you press most.
  2. Choose the key, then the target rule: your target, mouseover, or yourself.
  3. Add your other core spells the same way.
  4. Leave rarely used spells on the action bars. Clicked doesn't have to handle everything.

Forever status

Clicked's latest release on GitHub ships a Forever TOC, so it loads in Forever. Its page here has the version and date. For click-casting on raid frames, VuhDo has its own built in.
