Description

This has caused me many typos when typing fast. Is there a known workaround for this?

To repro:

  • Press and hold down a shifted keycode like KC_DOLLAR.
  • Press and release a non-shifted keycode like KC_1
  • The resulting output is $! but the expected output is $1

Contributor guide

Research direction
Examine the key state handling in `quantum/process keycode/process shift.c` and trace how shift modifiers are applied to subsequent keycodes in the matrix scan loop.
