 ```
 
 The novel part of this keymap is that it **preserves the default functionality** of the left alt key, so ```'alt + tab', 'ctrl + alt + del', 'alt + f4'```, etc. all work as expected without using any janky timers.

 This keymap was based on the 'default' Drop ALT keymap (and _not_ 'default_md') which means it supports all the fancy QMK RGB patterns, and isn't limited to the stock options that come with the board.
 
-It's also worth noting that this keymap fixes an outstanding issue where the caps lock LED flickers when the RGB mode is keylight or underglow. I could not find a general purpose fix, but the one included here works quite well.
