Remapping screen brightness keys to brightness in small steps does not work.


Before bug reporting, please make sure you have tried the latest (alpha) version of BetterTouchTool and that you have already tried to restart your system :-). If you encounter a crash, please attach a crash log from the macOS from the "User Diagnostic Reports" section.

Describe the bug

I am trying to set the screen brightness keys to change the screen brightness in small increments instead of the default behavior. I tried assigning the keys to the either the Brightness Down/Up (Small Step) shortcut, or the keyboard shortcut option+shift+Brightness up/down. The keys don’t respond and sometimes after a while, the accumulated keystrokes trigger the brightness to change.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
MacBook Air M2 keyboard
