Waldir Pimenta 4b7ef4a18d vim: improve examples (#1105) 
I tried to condense the most useful basic commands into this page without surpassing our length limit.
I also expanded the main description -- I wonder if there's a way to phrase it which could allow us to get rid of all the <Esc>s...

I combined copy/cut/paste into a single command, since it was important to allow space for a slightly more advanced command, (the find/replace example), which introduces some important vim concepts, such as command application ranges.

vim

Vi IMproved, a programmer's text editor, providing several modes for different kinds of text manipulation. Pressing i enters edit mode; the normal mode (accessed via <Esc>) doesn't allow regular text editing.

  • Open a file:

vim {{file}}

  • Enter text editing mode (insert mode):

<Esc> i

  • Copy ("yank") or cut ("delete") the current line (paste it with P):

<Esc> {{yy|dd}}

  • Undo the last operation:

<Esc> u

  • Search for a pattern in the file (press n to go to the next result):

<Esc> /{{search_pattern}} <Enter>

  • Perform a regex substitution in the whole file (from the start, 1, to the end, $):

<Esc> :1,$s/{{pattern}}/{{replacement}}/g <Enter>

  • Save (write) the file, and quit vim:

<Esc> :wq <Enter>
