You could have two boxes rather than one for selecting the current weapon set so that one could use a ranged weapon along with a melee weapon. Similarly we could implement two boxes for selecting the targeted spell type and the non targeted spell type.

Highlight the sword and press CTRL+F1 and then highlight the bow and press CTRL+F2. If you have a shield and your sword is single handed, you'll automatically equip a shield in the offhand while pressing the bound F1.
