Smart Actions and Profiles

This is the fastest path for most users

If you want to automate work on MX Keys or MX Master 3 without maintaining software, Smart Actions and app-specific profiles are usually the best first solution.

1. What Smart Actions are​

Logitech describes Smart Actions as multi-step automations triggered by a single click or keystroke.

The public Options+ pages specifically mention:

  • recording keystrokes,
  • application-specific actions,
  • adding URLs as text,
  • system actions like opening files,
  • delays between steps,
  • export and import of Smart Actions.

2. What they are good for​

Use Smart Actions when you want:

  • open app -> wait -> paste text,
  • launch a meeting setup,
  • mute camera/mic shortcuts,
  • coding workspace startup,
  • open terminals, browser tabs, and tools together,
  • simple text-expansion-like flows,
  • repeatable office tasks.

3. App-specific customization​

Options+ also supports app-specific profiles. Logitech's current pages list examples such as:

  • Chrome
  • Edge
  • Safari
  • Zoom
  • Word
  • PowerPoint
  • Excel
  • Photoshop
  • Premiere Pro
  • Final Cut Pro
  • Teams

That means your MX Master 3 button map or MX Keys function layout can change depending on the foreground app.

4. When Smart Actions are enough​

Stay with Smart Actions if:

  • the workflow stays on one machine,
  • the logic is mostly shortcut- and app-based,
  • you do not need external authentication flows,
  • you are not distributing the integration to many users,
  • the action can be modeled as a macro-like sequence.

5. When you need a plugin instead​

Move to a plugin when:

  • the integration talks to an external API or service,
  • you need custom configuration UI,
  • you want Marketplace distribution,
  • you need richer state handling,
  • you want dynamic actions rather than fixed shortcut sequences.

6. Practical examples for your devices​

MX Master 3​

Good fits:

  • thumb button opens Actions Ring,
  • gesture button switches app context,
  • one button runs a build/test/review startup macro,
  • app-specific mappings for browser, IDE, Figma, Excel, or Teams.

MX Keys​

Good fits:

  • F-key remaps,
  • workflow launchers,
  • meeting macros,
  • coding environment setup,
  • app-specific shortcut layers.

MK850​

Use it conservatively:

  • keyboard shortcut remaps if supported by your installed Logitech software,
  • simple office customization,
  • no assumption of current Marketplace plugin support.
