Mouse actions are actually supported in Via macros, just not in Via’s GUI

Today, I discovered that mouse actions in Via macros are actually supported! But a bug in Via’s GUI makes it impossible to enter them…

So how is it possible? By using the Via clone (but only if using a Keychron keyboard; it is supposed to take any keyboard’s JSON file as input, but I have never seen it demonstrated to actually be working). And the mouse actions actually work when the macro is executed.

Then in Via, the mouse keycodes are displayed as KC_MS_BTN1 (left click) and KC_MS_BTN2 (right click). But if trying to the modify macros they are in, we get (as noted in a previous blog post):

“Whoops! Invalid keycodes detected inside{}: KC_MS_BTN2”
