Your numpad sends F13 to F21, keys that OBS and most streaming apps can bind but no keyboard has, so nothing else will ever fire them. Bind each one to a scene, a source, or a sound.
Needs Rebind 3.5.0 or newer on Windows, macOS, or Linux. No extra permissions.
Set up
- Start the package.
- In OBS, open Settings > Hotkeys, click the field for an action, and press a numpad key. OBS records F13 to F21.
Settings
- Sends F13 to Sends F21: the key that sends each one. Defaults numpad 1 to numpad 9. Key changes apply while the package runs on Rebind 3.9 or newer; on older versions, restart the package.
Limits
- On Windows, turn Num Lock on. With Num Lock off, Windows reports the numpad as navigation keys, which this package does not catch.
- On macOS, numpad 9 is left alone because macOS has no F21; numpad 1 to 8 send F13 to F20.
- The numpad keys do not type numbers while the package runs.
- Live use remains unverified on Windows, macOS, and Linux.
Stop
Stop the package from the editor toolbar, or press Left Ctrl + Left Alt + K to stop all scripts.
