VIimit up(1)

Using Vim does not feel comfortable at first time even feel strange or wired. It recommend us to move cursor using four keys, h, j, k and l. ‘h’ and ‘l’ for left and right, ‘j’ and ‘k’ for up and down. The reason for this should back to the creation of Vi. When Bill Joy created the Vi text editor he used the ADM-3A terminal.

 

 

We can see there is no arrow keys on that. So i think this is the reason why Bill used hjkl keys for cursor movements. Details on http://www.catonmat.net/blog/why-vim-uses-hjkl-as-arrow-keys/
