For a preamble, please pardon my ignorance if I'm doing something horribly wrong, or if I have this filed incorrectly. So here's what I've observed: If I create two keyboard shortcuts, one triggered by Shift(In my case, Shift_L, but I doubt it matters), and the other by Shift+D(just any random key), then when I use Shift+D, both shortcuts activate. Furthermore, the shortcut bound to Shift activates on keypress rather than a more traditional keyrelease. Perhaps Modifier shortcuts should activate on keyrelease, as well as watch to make sure another key hasn't been keypressed in the meantime?
