I got tired of MacOS failing to index applications (it consistently seems to prefer apps installed on my phone instead of the computer) so I've bound them to keys and have started building muscle memory for opening and switching apps. Reduces mental fatigue from constantly cmd + tabbing between apps all day

Could you build this?
Partial While basic macOS shortcut apps are simple, tapping into raw IOHIDManager events beneath the OS input pipeline and modifying CGEvent taps requires nuanced macOS systems programming.
What it would actually take: The system requires a native Swift/Objective-C macOS application leveraging IOKit / IOHIDManager to listen to raw keyboard hardware scan codes before window server remapping, alongside CGEventTap to intercept and consume chords. The hard parts include avoiding latency spikes in the global event tap, maintaining accessibility permission states across OS upgrades, and rendering non-activating translucent overlay windows. This requires native Cocoa/CoreGraphics expertise that AI code generators frequently hallucinate or misconfigure.
