Using DEL November 6, 2017
The DEL key is used to delete characters as you would expect. It has one additional use. If entered as the first and only character on a command line it will toggle the use of the hostname in the prompt string.
The command line prompt displays both the hostname and the working directory/folder. Depending on the length of the hostname and what the current working directory may be the prompt can be lengthy. The DEL key can be used to shorten the prompt string by removing the hostname. The current working folder is always displayed.
