Okay, I'm trying to understand this and each link I've found is a dead end... So I'd like to make F7 serve as my "display all windows" Expose key. I looked at DoubleCommand, no luck. Looked at Uklele, which might be able to do the trick, but it's very confusing and I'm not quite sure how it's possible. Currently, it is possible to set up Expose with F7, but I must use Function + F7 (because F7 is designated for display mirroring). Anyway around this? Thanks.
