Uses a slightly modified version of inputbot: https://github.com/obv-mikhail/InputBot (added function is_down() under iputbot/src/windows/mod.rs)
If you initialize a hotkey with exactly 1 keyboard key: event will return true once the key is released, so 1 keypress returns exactly 1 true value.
If you initialize a hotkey with more than 2 keyboard keys: event will return true, once all hotkeys are pressed at the same time. It will be able to return true again, once at least 1 key has been lifted.
