Problem: Keeping track of your comments on GitHub, especially the most recent ones. A solution In the search bar at the top right, with “Type / to search”, paste the following in and press Enter: “desc” is for descending order. …
The short version: It is possible to change the number of Via and Vial macros and change the space for them to be essentially unlimited. Unfortunately, there are many different ways of achieving it, depending on the particular keyboard, the …

For instance, GitHub pages may be in dark mode when logged out and not when logged in. Sample GitHub page Change to dark mode When logged in, click on the profile picture in the upper right → Settings → Appearance …
The short version: A wireless QMK-based Keychron keyboard can provide the information about the battery state, e.g. “81%”, to the operating system, just like, for example, a wireless computer mouse. Though the operating system may have to be configured for …
Version 1.93 (August 2024 release, received 2024-09-05) fixed a problem with very slow (minutes instead of seconds) Git operations in Visual Studio Code. This problem was introduced with a recent release, probably the previous release one month earlier, 1.92 (July …

The idea is to capture the Via macro execution in function dynamic_keymap_macro_send() (in file quantum/dynamic_keymap.c) and instead feed the information into an existing QMK macro engine that has cancelling macros and repeating macros as features. Introduction It is relatively straightforward …

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: …

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 …
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 …

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) …
