Group of answer choices

A. Wildcard

B. The Tab key

C. Regular expressions

D. The Escape key

Answer:

When working with the command line prompt (cmd) on a Windows, Unix or Linux computer, typing file paths is sometimes difficult or considered to be a burden because they are lengthy (too long) and perhaps confusing to the user. To help yourself out, you can always use the "Tab key" to autocomplete names of directories or file paths in an alphabetical order, while in the command line.

<em>Additionally, pressing the "Tab key" continuously while in the command line would cycle or toggle all available commands in an alphabetical order. </em>
