I tried binding my 'H' key to 'Throw Item' but I could never get it to work. I went through the settings and, when trying to bind 'H' to any action, it highlights it in red but the description of the action is too long to know what it actually does (it shows up as 'Missing string STR').

But then I found out it shows the whole description if you click and drag the text and it shows up as 'Missing string STR_USRACT_MOVE_ITEM_FROM_HANDS_TO_INVENTORY'

This is a problem because this action shows up nowhere else when trying to reconfigure your key bindings making it impossible to unbind the action for the 'H' key.
