    3. Due to the inconsistent lowercasing of `event.key` on Mac and iOS when `Meta` is pressed along with `Shift`, it is recommended to avoid hotkey strings containing both `Mod` and `Shift`.
 7. `"Plus"` and `"Space"` are special key names to represent the `+` and ` ` keys respectively, because these symbols cannot be represented in the normal hotkey string syntax.
 8. You can use the comma key `,` as a hotkey, e.g. `a,,` would activate if the user typed `a` or `,`. `Control+,,x` would activate for `Control+,` or `x`.
+9. `"Shift"` should be included if it would be held and the key is uppercase: ie, `Shift+A` not `A`. Note however that MacOS outputs lowercase keys when `Meta+Shift` is held (ie, `Meta+Shift+a`); see 6.3 above.
