I set up a box to be unlockable via a key.

It works fine as long as I type the command:
unlock box

But when I use the typical adventure game construction of:
unlock box with key

I get a message along the lines of "Can't see that object here" which is very misleading. Is there an easy way for me to make it recognize the unlock...with construction, or is this a bug that needs to be addressed from within Quest?

Add a command with a pattern "unlock #object1# with #object2#".
