Answer:
The CTRL key
Explanation:
We use the CTRL key in our computers to randomly select items that we want to either copy, move, or cut. This key is used in files that have not been grouped together and have been placed separately from one another. Try it. Open a window that has folders in it. Select the first folder, for instance, hold down the CTRL key and select the third or fourth folder. Holding down the CTRL key will skip the second and third folder. As a result, you will have the first and fourth folder selected.
