Support calls are important and often satisfying in the end, but the act of clear communication can be arduous for everyone involved. If you[he]#039[/he]ve ever been on a support call, you[he]#039[/he]ve probably spent several minutes spelling out even the shortest commands and explaining in detail where the spaces and returns fall. While it[he]#039[/he]s often easier to just seize control of a user[he]#039[/he]s computer, that[he]#039[/he]s not really the best way to educate. What you might try instead is sending a user a screen recording, but one that they can copy commands from and paste into their own terminal.
