There are two types of people in the world. Those that use vi and those that use Emacs. --Unknown.
One should know only enough vi to compile Emacs. --Steph Bailey
I use emacs. In 1988, as a sophomore at the University of Chicago, I got a job working in the Computer Science Department. It was my first exposure to Unix, email and the Internet. The graduate students I worked with used Emacs, so I used Emacs.
Emacs is big; emacs is complicated. It took me nearly a year to figure out how to use the help system. It took me two years to figure out how to cut & paste a block of text.
This is stupid...
...and using a mode based text editor like vi...
...is more stupid.
Quit: ctrl-x ctrl-c
Save: ctrl-x ctrl-s
Save As: ctrl-x ctrl-w
Move forward 1 character: ctrl-f
Move back 1 character: ctrl-b
Move up 1 line: ctrl-n
Move down 1 line: ctrl-p
Ctrl-k will cut the text from the current cursor position to the end of the line. You can repeatedly hit Ctrl-k to quickly cut several lines of text.
Ctrl-y will paste the text "cut" with the ctrl-k command at the current cursor position.
