There are too many scales on brightness. Apple even allows users to press Shift+Option+F1/F2 to fine tune at a smaller step. However, I want to take a giant step. I want to press F1 to jump to 25% brightness, press F1 again to 0%. I don't want to use a slider. Using a hotkey in the keyboard is much quicker.

Is there such an app?

The built-in Shortcuts app can do this, and you don't need to code. Create a new shortcut, search for 'brightness', select it and change the value as needed.

Then click the Details button on the right. Click the 'Add Keyboard Shortcut' button, and press the keys you want to use to activate this shortcut:

Close the window, and the keyboard shortcut will work in all applications but Shortcuts.

  • That looks fantastic! However, it seems only Monterey has this built-in Shortcuts app. I use Big Sur on M1 macbook air. I only have 8GB RAM, and don't have the storage room for upgrading(19GB left). Plus, I am worried about compability with my softwares. Is there anothe way, for example using built-in Automator? I'm willing to learn a little code if it's not too complicated for an outsider.

  • That's a pity. I'm not familiar with Automator, sorry ...

I found an app called "Keyboard Maestro", which can achieve this function in my BigSur.

As shown in the picture below, I press F1 once to repeat "decrease screen brightness" 8 times.
