HelpItem quickslot rebind

I bound my 5 with something without remembering that it was a quickslot item button

Does anyone know if/what command I would bind to 5 to get it to use that quickslot 5 item again?

bind "1" "+quickslot1"
bind "2" "+quickslot2"
bind "3" "+quickslot3"
bind "4" "+quickslot4"
bind "5" "+quickslot5"
