from the "man csh" command of SunOS 4.1.2:
An event designator is a reference to a command-line entry
in the history list.
! Start a history substitution, except when followed
by a SPACE character, TAB, NEWLINE, = or (.
!! Refer to the previous command. By itself, this
substitution repeats the previous command.
!n Refer to command-line n.
!-n Refer to the current command-line minus n.
!str Refer to the most recent command starting with str.
Refer to the most recent command containing str.
Insulate a history reference from adjacent charac-
ters (if necessary).

absolutely ... Isn't Unix _great_!!!
As far as puting tcsh as a shell, if you are not root on your machine,
just ask your system administrator to do it ... it is very simple to do,
and if enough users ask, she or he will get arround to doing it ...
(I haven't yet, but only one user asked me so far ... ;)
