trigger is a key or key combination, such as 'H' and 'LSHIFT+H'. See List of Key Names for a... list of key names. Note: Chord keys (ALT, SHIFT, CTRL) are the only keys that can be added to create key combinations. You cannot create a key combo of 'NUMPAD1+RBUTTON'. /unbind removes a key binding and resets the key's action back to its default setting. Note: This is different from /bind trigger "nop" (nop is an abbreviation for "no operation").
