shell magic takeaways

There are lots of tcsh commands that help you navigate around when playing in the terminal.

Ctrl-a : back to begining of line
Ctrl-e: end of line
Ctrl-k: kills everything from the cursor to the end of line
Ctrl-b: moves cursor back (like the back arrow, but you don't have to move your hand as much)
Ctrl-f: moves the cursor forward
tab: completes the filename you are typing, very useful if you also set an environment 
variable in your ~username/.tcshrc file like this "set autolist" alone on a line. Try the tab with 
and without the environment variable. If you hate the beeping, put this environment variable 
on another line "set nobeep"
The up arrow: scrolls through last commands
!!: The last command
!$: The last word of the last command, really cool when you are doing something with a file 
Example:
% vi test.pl
% chmod +x !$
% !$
The shell will replace !$ with test .p
