-Step number 4 in Table 6.2 is critically important & deserves further discussion. In step number 4, you touch (or <​nowiki>"</​nowiki>​type<​nowiki>"</​nowiki>​) the command key.

 A common error for new users is to type the Return (or Enter) key after they type the command key. Com executes the command key fine, then it notices the Return key. Return is a command, so com executes it. The Return command gets you a prompt so that you may enter text that you <​nowiki>"</​nowiki>​say<​nowiki>"</​nowiki>​ for other people to <​nowiki>"</​nowiki>​hear<​nowiki>"</​nowiki>​ in the room. Because of the Return key, com is not interpreting the new user's keystrokes as commands. A common error for new users is to type the Return (or Enter) key after they type the command key.

 Then the new user tries to type another command, such as the ''​q''​ (quit) command, but com interprets it as text to say into the room. The new user is under the impression that he needs to end commands with Return, so he does that, which causes com to print ''​q''​ into the room for everyone to see. The new user is confused about why his command doesn'​t execute, so he types ''​h''​ & Return again. The ''​h''​ is interpreted as a command & gets him a menu, but the Return is also interpreted as a command & puts him into enter-a-line-of-text mode. He sees the ''​q''​ command in the menu, types it & Return, & the cycle repeats. Then the new user tries to type another command, such as the ''​q''​ (quit) command, but com interprets it as text to say into the room.
