Keyboard shortcuts are used by many users to accelerate their work on a Mac. A MacPad can go further to execute more actions with a single key. Dedicated devices can be costly. A standard Elgato Stream Deck costs more than a hundred dollars. A cheap numpad or extra keyboard can perform the same role for a fraction of the price.
Choosing your hardware
Any extra USB or Bluetooth keyboard works for macropad use. A small number pad is compact and offers ten keys plus a few modifiers. Some wired numpads retail for under twenty dollars. If you already have an old keyboard or numpad lying around, you save even more money.
Using manufacturer software or Via
Many keyboards come with configuration apps that let you record macros. Mechanical keyboard fans often use the free Via tool to remap keys and record sequences. In most apps, you simply select the secondary keyboard and assign a macro to each key. This method works without installing extra apps and supports up to sixteen macros for most numpads.
Going deeper with Karabiner‑Elements
Karabiner‑Elements is a powerful, free tool for macOS that can remap any key across all connected keyboards. After granting required permissions, you can set simple key changes or define complex rules. Complex rules let you trigger multi‑step scripts or mouse movements. Community‑published rules are available online, or you can write your own using the built‑in scripting syntax.
Adding Siri Shortcuts to a macropad
You can expand your MacPad’s power by linking keys to Siri Shortcuts. In the Shortcuts app on macOS, open a shortcut and add a keyboard shortcut under Details. Then remap a numpad key to that shortcut using your macropad software or Karabiner‑Elements. This unlocks tasks like smart reminders or app automation with a single press.
Tips for smooth setup
Test each key assignment in Notes or TextEdit first to confirm it does not conflict with your main keyboard. Keep a small reference sheet of your macros until they become familiar. Back up your Karabiner‑Elements or Via profiles to iCloud so you can restore them on a new Mac.
Using a spare keyboard or numpad as a macropad on macOS lets you create a highly personalized control panel without major expense. The combination of free, open‑source tools and low‑cost hardware gives everyone access to professional‑level shortcuts and automations. Once your setup feels natural, you will wonder how you ever worked without it.
