Emacs

Emacs is one of my favorite editor. After playing with some time i understand that,
as a programmer i felt life is very comfortable with Emacs.

Actually Emacs is purely written in Lisp, and I felt that lisp is good programming language. I tried things like chatting, remote file editing, sending mails from Emacs.

also I found a browser(conkeror), which works as Emacs for browsing.
meaning for opening URLs similar as file opening command in Emacs,
for searching also it's similar to Emacs. you don't need to use the mouse for this browser.
