// Cancel CapsLock when a Shift key is pressed.
//
// The usual workflow expected with this option is:
// - `<CapsLock>` ↓↑: `Caps` is locked
// - type caps letters
// - `<Shift>` ↓: `Caps` is unlocked, `Shift` is set
// - optionally type some more upper case letters: tolerance to sync with `Shift`
// - `<Shift>` ↑: `Shift` is unset
// - type in lower case
//
// A side effect is that both `<Shift>` keys together trigger CapsLock.
