    Project mention: Key, in sight [Creative uses of keyboard shortcuts and macros] | news.ycombinator.com | 2026-05-24

    Two notes:

    For buying new keys, there are many inexpensive (non-mechanical) USB number pads you can get for $10 or less. It's a good way to get started before committing to something more expensive.

    For software, Hammerspoon [0] is a free option that can handle arbitrary key mappings/macros; however, you'll have to program it yourself, it's more of a hacker's tool than something with a friendly UI.
