These gestures are also customizable by default they let you switch between multiple desktops (we appreciated this one in our testing), open the Start menu if you swipe up and reveal the desktop. In addition, pressing the gesture control on the thumb lets you trigger actions by moving your mouse in a particular direction, much as you would with multitouch gestures on trackpads or touch screens. The software comes with built-in presets for apps like Word, PowerPoint and Excel, making it a one-click affair to add relevant shortcuts tailored to the app you’re using (which you can still change afterward, depending on your liking). Using Logitech’s Options software, four buttons can be customized on a per-application or global basis. It’s a handy workflow assist you probably didn’t realize you needed. The thumbwheel comes set up for horizontal scrolling and browser tab swapping but can be customized on a per-application basis to do things like change brush size in Photoshop, scroll through the timeline in Premiere Pro or raise and lower the volume in Zoom. A small button below the wheel lets you swap modes manually. In our testing it was easy to jump instantly to the bottom of a long document and move incrementally once we got to the section we needed to edit. As with previous Master series mice, the wheel switches automatically between free spinning and precise line-by-line scrolling depending on how fast you move the wheel. The main wheel uses a technology Logitech calls “MagSpeed,” employing contactless electromagnetic switches rather than mechanical ones, for accuracy and long life. Right away, you’ll probably notice that the MX Master 3 has two scroll wheels: a main vertical wheel and a secondary thumbwheel. It’s such a nice feature that once you experience it, you’ll become painfully aware of how few other mice offer this support. It perfectly fits your hand’s natural resting position, with a wide, flared base that supports the base of your thumb. Nowhere is Logitech’s attention to ergonomic nuance more evident than in the design of the MX Master 3. Logitech MX Master 3 Eric Ravenscraft/CNN Your CNN account Log in to your CNN account
