Episode Details

Mapping a USB foot pedal to an unused key like F13 sounds simple until macOS drops F21 through F24, KDE claims F13 by default, and games ignore it. A more reliable approach is per-device interception, which identifies hardware by vendor and product ID. Tools like keyd, kanata, Karabiner-Elements, and AutoHotInterception let a pedal behave differently per app without colliding with your main keyboard—though deep driver-level remapping comes with its own risks, from config lockouts to Windows driver ID limits.
