My only problem with this is I don't normally hold the buckey key particularly long -- I strike the buckey key and selector key (i.e. an alphabetic) simultaneously and release. Holding it down would break decades of muscle / rhythm memory. This is the same reason I don't use key repeat. Hmm, I don't disable key repeat but never invoke it which confirms/reinforces my belief that I do a simultaneous strike. Perhaps others use their keyboards differently.
