Keybinding Problem... HELP!

[SW4NK3D]

So I just came back to the game to find out the EQ button has been removed, which was my main way to navigate the options. After some searching on how to get into the menus without this option I read several responses saying Alt+O is the keybinding I'm looking for. The problem here is the last time I played I was in the middle of unbinding all my keybindings and setting them up custom to my liking....and never got around to the "Toggle Options Menu" keybind...so its unbound along with all my other toggle menu binds. So how in the world do I now get into the keybinds to set those back up. Thanks in advance for any help given!
