From there, you can click on a button on the left and select or enter something to bind a key to. Once you've made your selection, click on the "Click to Set" button and enter a key combination.
Be sure to check that the spell, item, or macro name is correct, along with the key combination. Once you're satisfied with your choices, simply click "Set Key" and you're good to go. Overall, if you're in need of a no-frills solution for your key binding needs, SpellBinder is definitely worth checking out.
