How to Use Function Keys (aka Hardware Keys) as Triggers — Macro Library — Keyboard Maestro Discourse
Goal : Use the function keys to launch macros but only in RandomApplication. Keep their normal behavior everywhere else.
I keep my function keys defined as function keys on my iMac. On my MacBook Air I normally have the function keys assigned to their “hardware function” (e.g. Brightness Down, Mission Control, Pause, and Mute). This solution lets me keep the hardware function and use the function keys for custom control in Logic.
