Comprehensive search in QMK source in all branches, incl. forks and forks of forks
The divergence of QMK software development can be confusing, but there is a systematic way to find which branch a particular feature or folder is in (instead of manually switch to each branch and manually look for the information). Example: …

A hack to use mouse actions in Via macros
The short version: A relatively simple hack enables mouse actions in Via. Seldomly used keycodes, e.g., for F23 and F24, accepted by Via, are converted to the keycodes for left click and right click just before macro execution. This breaks …
Mouse actions in Via macros (QMK)
The short version: Mouse actions are not supported when recording macros, and they can’t be added after recording by inserting the appropriate keycodes in the JSON source (directly in Via, not in a file). Though there is a solution! Introduction …
Setting RGB colour for individual keys in QMK (per-key RGB colour)
The short version: in function rgb_matrix_indicators_kb() in file keymap.c, use function rgb_matrix_set_color(). For example, to set a blue colour on key F7 on a Keychron V5: That is for a V series Keychron keyboard (and presumably for all keyboards in …

Raw QMK keycodes (not symbolic)
Getting output from printf debugging for QMK is not worth much if it is not known what the QMK key codes actually are. That is, actual numbers, not the symbolic names in the source code. Some QMK keycodes (raw numbers) …
QMK debugging blues on Ubuntu: hid_listen
The short version: Building the third-party tool “hid_listen” from source and using Ubuntu 20.04 (Focal Fossa) or later enables debugging of QMK firmware on Ubuntu. Introduction Printf debugging is enabled in QMK by using the standard printf (or its cousin dprintf()) …
The basis for a way to cancel QMK macros in progress
The short version: Use QMK‘s send_string_with_delay() with binary content (as it is not a real string) encoded in a particular manner to piecemeal execute a macro, housekeeping_task_user() to run a state machine for executing the macro (which can check for …

Via macros (on mechanical keyboards with QMK) are less crippled than expected, e.g., unlimited number of key actions in macros
For example, the total number of key actions available to macros defined in Via can be increased from about 150 to use most of the free flash memory, using emulated EEPROM memory (or possibly be limited by the RAM (used …
Keychron V5, a reasonably priced fully macro-capable QMK-based mechanical keyboard
The short version: The Keychron V5 mechanical keyboard is fully capable of macros, including mouse operations (e.g., right-click). This is enabled by the use of QMK and the length of macros is only limited by the available flash memory in …
