Removing unwanted apps/things from your apple ID

Hello,
I'd like to permanently remove apps/other things I've mistakenly downloaded to my apple ID. in other words, I've downloaded some games, thinking they were good for people with visually impairments--myself included--however, I can't remove them from my ID itself through iTunes? I can only unhide them, but I'd like to totally remove them so they're never visible again, of course, other than in the billing cycle to which my ID is connected/Discover card, that is. if I'm not making any sense here, please let me know.
Thanks,
Ashleigh Piccinino
P.S. What I'd like to do is remove the apps/other unmistakenly downloaded things permanently from iTunes/the whole apple ID system on my computer. To that end, I of course use JAWS, so I'll need the keyboard shortcuts and things to help with this.
