Does having hotkeys take an async function make sense?

New to asyncio stuff, but does having ahk.add_hotkeys take an async function make sense? Right now it does not seem to work "quietly".

The callback is simply a callable. Although an async function is technically a callable, calling an async function merely produces a coroutine which must be awaited, so this is likely not what you want to do.

If you must call an async function for your callback, you can use different strategies to work around this, (for example, calling asyncio.run in a regular function) but ultimately, you want to be passing a regular function to ahk.add_hotkey.

Without knowing exactly what your code looks like, a simple solution might be to do something like this:

async def my_async_function():
    print('My async function starting')
    await asyncio.sleep(1)
    print('My async function done')

def my_callback():
    asyncio.run(my_async_function())

ahk.add_hotkey('#n', callback=my_callback)
# ...

Keep in mind that hotkey callbacks each run in their own thread, anyhow.
