Hotkey Rememberer?

[CHASE6]

Hi All,

 

I swear I used a mod with the title of this thread. Say if you have a sword hotkeyed and you have it knocked out of your hand, when you pick it back up it's back in the hotkey spot and you can re-equip. However, I can't even find a mention of this on google, let alone here. Any ideas?

 

Thanks
