Programmable Buttons are keys that have no predefined meaning. This means they can be processed on the host side by custom software without the operating system trying to interpret them.
The keycodes are emitted according to the HID Telephony Device page (`0x0B`), Programmable Button usage (`0x07`). On Linux (> 5.14) they are handled automatically and translated to `KEY_MACRO#` keycodes (up to `KEY_MACRO30`).

?> Currently there is no known support in Windows or macOS. It may be possible to write a custom HID driver to receive these usages, but this is out of the scope of the QMK documentation.
