ctrl+shift+alt+g no longer brings up VideoFX

dont know how I did this (I suspect I probably remapped this a week or two ago and forgot) but now the keycombination no longer brings up the menu...

does someone know how to reset this?

On the General Tab of the Character Set, tick the checkbox for "In-game ISBoxer GUI toggle hotkey" and enter a keybind.
