Keep the number keys as moving around, but ween yourself off using / as... info? or whatever... it's useless as info, swap it over to a bolt and it'll be great. As long as it's a targeted spell, if there are no valid targets you'll just prep it, and not cast, no danger there.
904, 906, 908, 910, 505, 516, 518, and 519 fill out the /, *, -, + and ctrl versions of those keys quite nicely.
