Vim - navigating the file by single character

    ^
    k
< h   l >
    j
    v

h - left
j- down
k - up
l - right

If you want to move several positions, but do not want keeping hitting the same key over and over again - you can simply hold it down and it will start to repeat.

The above commands can be preceeded by a number. Example:
21l - move 21 chars to right
