Its the last day of prototyping so I want to learn vim.

Riviera says just type

vim tutor 

but spoken language is hard so I made a file called tutor by accident. Then you need to press

:qa 

to get out. Then I types

vimtutor

and I can do the tutorial.

letters hjkl to move around.

:q!

is the same as

:qa

is the same as

:q 

? I think I dont know difference yet. Maybe something to do with saving. This quits without writing.

x

delete character

i

is insert (ESC to exit insert mode)

A

append

:wq

write and quit

dw

delete word (til start of next word)

d$

delete to end of line

de

delete to end of word

operators and motions. d is the delete operator, w (until start of next word), e (until end of current word) and $ (until end of line) are motions.

3w

Typing only a motion (or a multiple of it by putting a number before) moves the cursor by that distance

0

go to start of line. oh this is fun I like it.

dd

delete line

2dd
d2d

both delete two lines.

u

undo

U

undo all changes to most recently changed line

CTRL-R

redo
