Description of issue: So forge allows you to modify your key binds by combing it with modifiers like shift, ctrl, and alt. Right? So, I'm not sure if this is a bug, but I'm gonna provide a quick example of a problem that I'm experiencing. So I have one of the controls, quick cast, from Iron's Spellbook mod, as a demonstration, and I've set it to Shift + 1. It does work, but if I press Shift and 1 at the same time, it creates a problem where every time I press shift, it executes the quick cast control without me pressing 1 with the shift.
