Handy Addon called BindingsReminder

What it does: Whenever you go you the Key Bindings Screen, this addon opens a window with a Virtual Keyboard BELOW the original Keybind List, so you can quickly glance and Mouseover any
of the keys and see what commands and Modifiers (IE Ctrl, Alt Shift) are assigned to those keys, it also shows you keys that don't have any bindings etc.
Very helpful if you also use the Spellbinder addon, or the looting and/or quest accept macros
