Detecting repeat key presses when the user is holding down a key? about global-hotkey

It should be possible on Linux and Windows but idk about macOS, there is a lack of documentation around the APIs, the only thing I could find is https://github.com/planetbeing/xpwn/blob/ac362d4ffe4d0489a26144a1483ebf3b431da899/idevice/QuicktimeSDK/CIncludes/CarbonEvents.h#L943-L951 and it doesn't seem possible.

What is your use-case for repeated events? I believe you can simulate the repeated keys by looping until a released event.

Apologies for the late reply and thanks for your help. This does seem to work quite easily on Windows as you mention but indeed I have never tried such a thing on macOS.

In my case, I am registering a global hotkey for controlling the volume of an audio interface using the volume up/down keys. As you can imagine, much like Windows' native volume control, it is very common to hold volume up or down to reach the desired volume.

Presently I'm using the native Windows API calls myself but would love to use your cross-platform implementation.

We can add repeating behind a feature flag or an option on the GlobalShortcutManager but would only work on Windows and Linux. We can maybe emulate the repeating behavior on macOS but what should be the frequency?

On Windows, this can be configured via the OS itself:

So I think it optimally would be configurable for OSs that don't support it natively.

What do you think?
