Even though I’m a die-hard Emacs user, there are times when I have to use the vi editor — specifically gVim, the graphical face of the popular vi clone Vim. Since I use gVim so infrequently, I don’t readily remember many of the editor’s basic commands. Either I muddle through or reach for my well-thumbed copy of the vi Editor Pocket Reference. That was until I discovered Cream. With Cream, gVim becomes an easy-to-use editor — so easy, in fact, you might not believe that you’re using vi.
