I run my computers keyboard-first. On my Mac, Caps Lock becomes a "Hyper" key. Hyper plus a letter opens or jumps to an app, or fires an action without touching the mouse. That includes capturing the YouTube video I'm watching, saving a LinkedIn post to my notes, and starting a voice memo. I've built the same kind of shortcut layer with Raycast, which also handles app launching, clipboard history and window management. On Windows I set it up with PowerToys, so the same habits carry across both machines.
This is a workflow I configured around existing tools, not a claim that I created Hyperkey, Raycast, or PowerToys.
