Cancels held down key.

Works great but if the key chatters on a stroke where you're holding down, it will be as if you're not holding the key down at all.

Hi @xeon826. I can't confirm this myself as I'm not using Linux anymore, however, while holding the key, the keyboard emits different events compared to pressing the key. I am specifically not filtering key hold events at all.

Just to be clear, as far as I know, the "key is being held" state is tracked by the keyboard itself. Just because the key down was filtered by the PC doesn't mean there will be no key hold events later.

I am not sure of this, but it may be that your keyboard itself, because of its chattering issue, is detecting the key as not pressed and not sending the hold events.

In case the issue really is with the tool, you or anyone else are welcome to submit a pull request, which I'm not sure what it should do to be honest. In any case, I can't test the tool myself right now.

in my case holding the down key has a small lag, but I just keep it pressed and it works

my Keyboard: Logitech G413
OS: Linux Mint 21.3

Had the same problem. To fix you have to replace the following lines in filtering.py

# some events we don't want to filter, like EV_LED for toggling NumLock and the like, and also key hold events
if not event.matches(libevdev.EV_KEY) or event.value > 1:

with this:

# filtering keys that are held down for combinations disable said combination from working (i.e. shift+d for D)
blacklist = event.matches(libevdev.EV_KEY.KEY_RIGHTALT) or\
        event.matches(libevdev.EV_KEY.KEY_LEFTALT) or\
        event.matches(libevdev.EV_KEY.KEY_RIGHTSHIFT) or\
        event.matches(libevdev.EV_KEY.KEY_LEFTSHIFT) or\
        event.matches(libevdev.EV_KEY.KEY_RIGHTCTRL) or\
        event.matches(libevdev.EV_KEY.KEY_LEFTCTRL)

# some events we don't want to filter, like EV_LED for toggling NumLock and the like, and also key hold events
if blacklist or not event.matches(libevdev.EV_KEY) or event.value > 1:

I tried to do a pull request but I am to tired to figure it out right now. Maybe tomorrow or later
