MX Anywhere 3S on Mac — Portable Mouse, Full Mapping

The MX Anywhere 3S is the travel-sized cousin of the MX Master 3S — no Thumb button, no Wheel Tilt sensors, but the four inputs it does have get every LinguaX gesture type. Push-to-talk on a side button, Space switching by swipe, per-app input-source switching — all fit on a mouse you can slip in a laptop bag.

What you can actually map on the MX Anywhere 3S

LinguaX exposes four configurable inputs on the Anywhere 3S, plus Left / Right which macOS handles directly:

  • S1 / S2 (side buttons) — the two thumb-side buttons (default Back / Forward). Full four-gesture layer: click / double-click / long-press / directional swipe.
  • M (wheel click) — the middle button.
  • SM (Scroll Mode) — the small button behind the wheel that toggles MagSpeed between ratchet and free-spin. LinguaX lets SM carry a second action while still toggling wheel mode.

The Anywhere 3S has no dedicated Thumb button (that is exclusive to the MX Master line), and no Wheel Tilt — the wheel presses down for a middle-click but does not tilt sideways.

What Options+ can't do on the Anywhere 3S

Even with fewer buttons than a MX Master, LinguaX still gives you what Options+ leaves on the table:

  • Push-to-talk on a side button — long-press with a 200 ms threshold as a physical PTT switch.
  • Four-direction swipe on the side buttons — Options+ fires on press; LinguaX distinguishes swipe-left / -right / -up / -down as four independent actions.
  • Per-app overrides by bundle ID — same side button, different action per app. See App-Scoped Overrides.
  • Modifier-hold — treat a side button as "held Cmd" while pressed.
  • No account, no cloud sync, ~10 MB native.

Three ready-to-copy setups for a portable mouse

1. Push-to-talk on S2

Since the Anywhere line has no Thumb button, use S2 (Forward) for PTT — Forward is less muscle-critical than Back for most browsing habits:

  • S2 long-press (200 ms) → Hold the shortcut your voice tool uses (Superwhisper Fn, Wispr Flow , Zoom Space)
  • S2 click → keep Forward for browsing (short click still fires the default)

Details: Push-to-Talk Voice Typing on macOS with a Mouse Button.

2. Space switching with S1 swipe

  • S1 swipe-left⌃ ← (Space left)
  • S1 swipe-right⌃ → (Space right)
  • S1 click → keeps default Back action

Two or more Spaces reachable with a thumb flick, no reach to the trackpad or keyboard.

3. App-scoped side-button behaviour

Same button, different action depending on the frontmost app:

  • Global: S2 click → Forward
  • In Zoom: S2 click → Mute toggle
  • In your browser: S2 double-click → Reopen closed tab (⌘ ⇧ T)

Configuration reference: App-Scoped Overrides.

Setup in three minutes

  1. Install LinguaX from Installation.
  2. Pair the mouse. For travel, Bluetooth is usually better — no dongle to lose. Pair via macOS System Settings; the Anywhere 3S supports three Easy-Switch slots so you can also pair a Bolt receiver at a permanent desk.
  3. Open Mouse+. LinguaX recognises the Anywhere 3S via VID:PID and shows the S1 / S2 / M / SM slots.
  4. Apply a recipe. Start with push-to-talk on S2 — it is the biggest productivity win a portable mouse can offer.

If your workflow is mostly stationary, the MX Master 3S gives you three extra mappable inputs. If you carry a laptop bag, the Anywhere 3S trades those slots for portability — the four it has still cover push-to-talk, Spaces, and per-app overrides.

Compatibility notes

  • HID++ 2.0 — recognised natively with full profile support.
  • Battery — shown in the tray for both Bluetooth and Bolt connections.
  • Sleep / wake — auto-recovers.
  • Three Easy-Switch hosts — LinguaX keeps a separate profile per host.

FAQ

Does the MX Anywhere 3S have a Thumb button? No — the Anywhere line drops the Thumb button that MX Master models have. Four configurable inputs: S1, S2, M, SM.

Can I still do push-to-talk on the Anywhere 3S? Yes — bind long-press to S2 (Forward, less-used than Back). Same 200 ms threshold as the Master line.

Bluetooth or Bolt receiver for a portable mouse? Bluetooth for travel (no dongle to lose), Bolt for a permanent desk. The Easy-Switch button toggles paired hosts.

Does LinguaX show battery for the Anywhere 3S? Yes, via HID++ over Bluetooth or via the Bolt receiver.
