Ok, I figured it out. I like Microsoft ... It can work with any external mouse that supports three buttons. I use a Microsoft USB wireless mouse with three buttons, with average support for the scroll function (wheel). If I hold the left or right mouse button down, and then press the scroll wheel, a showdown will appear. I can also release both buttons so that if I use my scrolling, I can choose which application I want to focus on (or just click on the desired application). The only thing I didn’t understand was that when this happened for the first time, applications surrounded my desktop in denunciation. This time they just appear as an organized grid.
