Vibes of vi

Well, as a real late bloomer into the Linux distro I've suddenly gotten an urge to use VI. A command based text editor. I started learning it today using the page [ How to use the vi Editor ]. A really nice tutorial to kick it off. At first I thought "Why?? When I have so many good editors that know what a mouse is and have integrated command line support??". The answer came in when I first use the command

cw 

It immediately caught my attention, what I could do with it. I could use it in my coding for so many occurrences. Whenever G++ served me with any error, I could search for it using

/ (slash)

And replace it with this command.
I'm currently learning more detailed stuff on this. Hope to replace GUI based IDEs with it someday.
