Add --clearmodifiers to xdotool so held Ctrl/Alt don't corrupt the simulated Ctrl+` into Ctrl+Alt+`. Also add 50ms delay before stop to let key release propagate to X11. https://claude.ai/code/session_01XKYC1basxdwtHy71tky7xm

openwhispr-ptt.py — Push-to-talk wrapper for OpenWhispr

|
Turns Ctrl+Alt (hold) into Ctrl+` toggle pairs using raw evdev input.
|

No key repeat issues — reads physical key state directly.
|

|
|
Requires: evdev, xdotool
|

May need to run as root or add user to 'input' group.

Usage: sudo python3 openwhispr-ptt.py
