files - basic file handling commands editor - text editor; must know about files first vi - screen-oriented text editor; must know files first morefiles - more on file manipulations and other useful stuff macros - "-ms" macros for BTL memos & papers; must know editor eqn - typing mathematics; must know editor C - writing programs in the C language; must know editor This is probably the proper order, but after you have the "files" course and know the basics of "editor", try anything you like. Note that the "vi" lessons may have to be installed by your system administrator. You can always leave learn by typing "bye" (and a RETURN). You can stop it from typing by pushing interrupt (or break or rubout or delete, depending on your terminal). If it won't accept your answer, and you _k_n_o_w you're right, answer "no" when it asks whether you want to try again, and it will go on to the next lesson.
