Vi

Quick reference for basic editing in Vi

go into insert mode, here you may use arrows to navigate text, and edit it with the keyboard as normal:

i

exit insert mode:

Esc (the escape key)

WHEN NOT in insert mode you may use:

write changes:

:w   (then enter)

exit vi:

:q   (then enter)

exit vi without saving changes:

:q!   (then enter)
