The Mac system can create multiple desktops. I am used to opening three desktops. The first desktop is for entertainment windows such as browsers and QQ, and the second window is for programming tools such as Xcode. Put some notes in the three windows, tools or something.
Generally, when switching, you may know Ctrl + left and right arrow keys to switch. If you open multiple desktops, you have to cut them continuously. Of course, you can also open MIssion Control to switch, but it is a bit troublesome.
In fact, Mac can directly use Ctrl + number to switch the desktop, the steps are as follows:
1. First you have to have multiple desktops (seems like nonsense).
2. Open System Preferences - Keyboard - Mission Control (as shown)
3. If there are multiple desktops, the shortcut keys at the bottom will appear, just tick it.
In this way, you can use Ctrl + number keys to quickly switch the desktop (the number of shortcut keys increases with the number of desktops)
