VI

Cheat sheet

Visual mode	Shift + v
Visual block Mode	Ctrl + v
go to line 55	55 gg
G	Go to the end of the document

Block comment/uncomment

Comment: Go into visual block mode
shift-i to insert, add a # (or any other comment sign)
the symbol appears in the first line
esc and it gets copied on every line (it happens only after the -esc !!)
Uncomment: Select in visual block mode and delete.

Indent

In normal mode, type >> to indent the current line, or << to unindent. Each command can be used with a count. The operators > and < do the same for motions, text objects and visual selections. For all commands, pressing . repeats the operation.

For example, typing 5>>.. shifts five lines to the right, and then repeats the operation twice so that the five lines are shifted three times.

In insert mode, Ctrl-T indents the current line, and Ctrl-D unindents.

When indenting or unindenting, lines are shifted one 'shiftwidth' to the right or left.

:set shiftwidth=4
