Moving around in vim is a basic but import thing. In my mind, if you can move to the place you want to insert a word, you are in the right track to use vim. please get ride of "up,down,left,right" arrow and use "h,j,k,l"
The most basic movement is showed in the picture below:h,j,k,l

also you can add a number before them like: 2h, 5j to repeat several times
^ ---- start of line
$ ---- end of line
ctrl-b ----one screen backward
ctrl-f ----one screen forward
G ---- end of a file
gg---- start of a file
H ---- first line of the screen-
M ---- middle of the screen
L ---- last line of the screen
ctrl -o ---- start a new line after this line
ctrl -O ---- start a new line before this line
w ---- next word
e ---- end of word
b ---- back one word

this is the notes for today, tomorrow Moving around part 2 about
sentences, paragraph and change between upper case and lower case

This is a test from vimrepress.
