Tricks of Emacs

Tired of emacs' black on white color theme ? Try white on black (see a snapshot)!

(set-foreground-color "white") 

(set-background-color "black")

Since version 22.1.50, TRAMP has been integrated within emacs to provide remote editing facilities.  Given that you have an account user on remote computer machine.domain.org, to edit file /home/user/foo remotely enter:

/ssh:user@machine.domain.org:/home/user/foo

This will open a connection to machine.domain.org, load file /home/user/foo and commit changes each time you save the newly opened buffer. See the TRAMP manual for more features (other protocols than ssh, password caching, multiple hops etc.)
