"Here is your 5 minute tutorial. The easiest way to learn vi is to know what the letters stand for:"
y(ank) - copy d(elete) - delete c(hange) - change p(aste) - put from buffer after cursor o(pen) - start a new line i(nsert) - insert before current character a(fter) - insert after current character w(ord) - moves to beginning of next word b(ack) - moves to beginning of current word or prior word e(end) - moves to end of current word or next word f(ind) - moves to a character on the current line movement keys you just need to learn: h,j,k,l ^ - beginning of text on a line $ - end of text on a line 0 - first position on line most commands can be prefaced with numeric modifiers. 2w - means move 2 words 5h - means move 5 charcters to the left 3k - means move 3 lines up 3fs - means move to the 3rd letter s folling the cursor modification commands (d,c,y) need to know how much to work on. dd - delete a line into memory yy - yank a line into memory cc - change the whole line c$ - change from current position to the end c2w - change the text spanning the next 2 words 3dd - delete 3 lines d2f. - delete to the second period. . - means redo the last modification command. / - searches for text, and then n(ext) will go the next found occurance. N will go prior. ? - searches backwards through the document.
