Macros

Yes8Maker product pagefutureisnow.logitech.com/en-ca/software/logi-options-plus/smart-actions.htmlRead 21 October 2026Logitech describes Smart Actions as automating multiple actions with one click, like macros with a little magic. The page features the Pebble Mouse 2 M350s as a supported device. Trusted Reviews calls them essentially macros assigned to the middle button. The macros run from the software, not from mouse memory.9Reviewtrustedreviews.com/reviews/logitech-pebble-mouse-2-m350sRead 21 October 2026Review text: Smart Actions are essentially macros that you can assign to the middle button.
