"AFK" may not be a recognizable term to everyone

[maneesha]

How could the content be improved?

In the typical work session exercise, the last step is to "celebrate" with "AFK."
I am assuming this means "away from keyboard" but everyone may not know this, especially because everything else in that exercise is an actual shell/git command and it may cause confusion to think that "AFK" may also be a command they should know.

Which part of the content does your suggestion apply to?
