How to refresh the computer keyboard?

Pressing F5 on the computer keyboard is a refreshing function.

Refreshing purpose

Refreshing means that after a period of time, information may be lost and need to be rewritten. In order to make the information stored for a longer time, the information stored in each memory cell must be constantly refreshed, that is, the data in each memory cell is read out and then written back to the meta cell to charge the capacitor in each memory cell.

For example, if there is something wrong with the graphics card or application, you can use refresh to restore the display. Sometimes the display items about Explorer in the registry will be modified. If you want the changes to take effect immediately, you can also use refresh to reload the resource manager, so that you can see the effect of the changes immediately. In addition, if there is a problem with the display, and the refresh failure cannot be recovered, you can restore the normal display by reloading the Explorer process.

The refresh behavior on the desktop actually plays the role of refreshing the current file display information, because the desktop itself is also a document folder (in the desktop folder in the user account folder under the system disk), but this folder is special, so clicking refresh on the desktop actually plays the same role as clicking refresh in the folder.
