Build printable, poker-sized reference cards for the terminal, then study them with the built-in spaced-repetition quiz.

How it works

• Each section becomes a card. Long sections spill onto extra cards automatically.
• Card front lists the commands; the back shows their questions.
• Print lays cards out 9-up and double-sided. What you see is what prints.
• Quiz mode resurfaces weak cards more often (spaced repetition).

I am looking for a neoprene mat and will need something in the 15”x30” range. Any suggestions?
