showing relative line number in vim
Being a long time vim user, this is the first time that I heard vim supports relative line numbers, by which users can jump around the editor screen even more quickly. Just type :set rnu will do the trick.
Another good plugin that can improve navigation speed is EasyMotion. It works a bit like the "f" feature in vimperator for firefox. Too bad that it's not avaible for intellij's ideavim.
