Shoutout to Shortcat for providing something like "knowledge-free keyboard shortcuts everywhere" on macOS. You hit a search key-chord (I use SHIFT-CMD-SPACE) and it pops up a search modal making all UI elements keyboard selectable. Usually the thing you want is 1 or 2 characters followed by Return.
It honestly reminds me of the experience of navigating Windows menus with Alt- and progressive keyboard shortcut learning, but flexible enough to handle things like Electron applications that don't even have a Menu bar or settable shortcuts.
Does anyone else use this or something similar?
