Guess I'll add some life to the topic aswell
Now it is true that the script supports a methode of shortcut keys.
Though the request you make can not be done with this script, I'm afraid (and very sorry).
Linking to a skill or item or other sub-component will require addition code and conditions since they act differently.
For example: Linking a skill to a hot key requires it to check if it is allowed to be cast (can't be cause on map for example, or you'd need a map-battle-system).
I'm pretty sure I've seen other scripts do just that going around the forums somewhere.
I'm sorry that the script didn't do what you'd hope it would.
My motto used to be that my scripts were as compatible as they could be, so they could be used with any other propperly scripted scripts.
Now this might not have been applied to this script, since it was one of my earlier ones.
I'm known a bit with Yanfly's work and I have to say, it's a shame that the feature that my script adds to the game, isn't implemented her menu system script.
I also have to say that the scripts Yanfly makes, aren't really optimized to be used with other scripts since they should provide a huge library of functionalities (shamefully not the one of shortcuts and such).
I'm sorry to say, but it would be up to Yanfly to add the functionality or make her script compatible with this one
Goodluck and greatzz,
