Fixed StringUpper and StringLower to work when OutputVar is the clipboard (broken by v1.0.45). [thanks songsoverruins]
Fixed the hotkeys ~Alt, ~Control, and ~Shift to fire upon upon press-down rather than release (broken by v1.0.44).
Background: Without the tilde, Alt/Control/Shift fire upon release to avoid taking over both the left and right key. But a specific left/right hotkey like LAlt or RShift fires upon press-down.
