Piping was something she remembered too: she wanted to pipe the file contents to say to hear the funny mumbo jumbo recited by Alex the Default Voice. Typing the pipe character was easy but remembering alt-7 will take some more practise.
The new thing this time was deleting rows in vim (type "dd"). It was fun and many rows were deleted.
Still, remembering the names of the commands vim, cat and say is hard. More practise needed.
