How to quickly open the Charm column in the Win10 system

After many people use the Win10 system, I found that some things in the previous Win8 or Win8.1 are gone, and some of them still have quite a lot of users like it. For example, this Charm column does not completely disappear on Win10, we can still open it.
Open method
Press the Windows key +C to start the Charm column of the Win10 system.
If you are used to automatically hiding the taskbar, then use this shortcut to quickly launch the Charm bar, you can easily view the time and date. And it's still quite meaningful to be able to quickly use the features of the charms.
