A Script request involving items

Hello;

I have little knowledge of available scripts for this program, but what I'm looking to do is fairly simple. Say I am on the map, and have a silver key and it needs to open a silver door, I want to force the player to open his inventory and select the key instead of automatically just opening the door. I think that this could add a lot more interaction via more choices. Is there a script that does this?

Thanks.

maybe a well made event can do this. Again most know eventing is my WEAK point..next to grammer and stuff. But their is a event called "Call menu screen" maybe that helps.
