`!$`	the last word of the previous command (same as `Alt` + `.`)
`!$:p`	print out the word that `!$` would substitute
`!*`	the previous command except for the last word (e.g. if you type ‘find some_file.txt /‘, then `!\|` would give you ‘find some_file.txt‘)
`!*:p`	print out what `!\|` would substitute
`~TABTAB`	List all users
`$TABTAB`	List all system variables
