// Alt: Keep if Alt is pressed or if the key isn't an Alt key
// Example: If altKey is true, keep all modifiers
// If altKey is false, filter out 0x04 (AltLeft) and 0x40 (AltGraph)
// If altKey is false, filter out 0x04 (AltLeft)
//
// Special case: Despite the Alt-Gr key being pressed, `altKey' on
// the event `e' is set to `false'. This means we cannot detect if Alt-Gr
// is being pressed while the user e.g. presses the `2' key. Instead, we
// we need to rely on keyUpHandler/keyDownHandler to toggle the state
// for 0x40 (AltRight) and avoid filtering for this code here, so that we
// can remember the state of the Alt-Gr modifier on subsequent key presses.
