Opening ManPages and Documentation in Vim

Vim has this awesome feature for referring to the documentation of a command or functions.

To get the documentation or the man page of a command or a function from within vim, Go to your command or function and press

Shift + K 

To Check for this yourself :

Open your Vim editor with some file

vim testVim.c

Type in some commands or functions

scanf("%d",&a);

Move your Vim cursor to the 'scanf' and press 'Shift+K'

You will be presented with this awesome manPage(documentation) for the scanf function.

This can be carried out with any commands or functions.

Shift+K basically presents you with the documentation associated with the command in your file.

How cool is that ? :)
