Running Cursor's Review Loop With Your Feet
Pedal Three is a three-pedal USB foot switch, and the standard way people configure it for a coding agent is one pedal for accept, one for reject, and one for push-to-talk, covering the repetitive half of reviewing Cursor's suggestions without your hands leaving the keyboard. Because it enumerates as a plain USB keyboard, it works the moment you plug it in; reprogramming what each pedal sends is a separate, optional step.
What exactly would each pedal do in Cursor?
Whatever you program it to send: a single key, a modifier combination, a whole text string, or a mouse click. Cursor's review loop has you stepping through inline edits and multi-file changes and accepting or rejecting them in the editor, and since that action might be a keystroke or a click depending on how your setup exposes it, the pedal's ability to send either is what makes the mapping work. Pick whichever input actually triggers accept or reject on your machine, and program the pedal to send exactly that.
How much does this actually save, in your own numbers?
Count how many times a day you review a Cursor suggestion and reach for a mouse or a key combination to accept or reject it. If that number is in the dozens, each one is a small hand movement off the keyboard and back; multiply your count by however long that round trip takes for you, and that's roughly the time and attention a foot pedal is trying to claw back, since your feet are otherwise doing nothing during that loop.
Does the third pedal work well for push-to-talk?
Yes, if you're pairing this with a dictation device rather than typing prompts by hand. Hold the third pedal down while you talk into a keypad like the Voice Pad or Whisper Key, and your hands never leave the keyboard for either half of the loop, briefing or reviewing. You don't need a dictation device to make use of the third pedal, though; plenty of buyers map it to something else, like a second confirm action or a shortcut for the next file.
Does the three-pedal switch need a driver?
No, not to use it; it enumerates as a standard keyboard, so any operating system accepts it immediately with whatever it was last programmed to send. A driver only enters the picture if you want to change those mappings, and the configuration utility for that is Windows-first. The pedals themselves work the same on macOS and Linux, so the easiest path is to program it once on a PC and carry it to whatever machine runs your Cursor sessions.
When is a fourth pedal, or no pedal, the better call?
If you find yourself wanting one more action mapped, running tests, jumping to the next diff, the four-pedal version covers that without changing anything else about the setup. And if you review Cursor's suggestions only a handful of times a day, or you're not bothered by moving a hand to click accept, the honest answer is that a keyboard shortcut does the same job for free. Pedals carry a higher US duty class baked into the price, so they earn that back only if your accept-or-reject count is genuinely high. Compare the rest of the lineup under Cursor hardware guides.
