Settings to remember when I need to use tcsh in a foreign environment:

set prompt="%/ > "
# set prompt="%{\033]0;%M: %c\007%}%/ > "
set complete=enhance
set autolist=true

set colorcat
setenv GREP_OPTIONS --color=auto
setenv GREP_COLOR 32

Copy the above lines to $HOME/.tcshrc. The first 3 are the most important ones to remember. Setting prompt to "%/ > " puts the $cwd in the front of the command prompt. $cwd is the same as the all-upper-case $PWD but is easier to type.

To list current key bindings in tcsh:

$ bindkey
"^A"           ->  beginning-of-line
"^D"           ->  delete-char-or-list-or-eof
"^E"           ->  end-of-line
"^I"           ->  complete-word
"^J"           ->  newline
"^K"           ->  kill-line
"^L"           ->  clear-screen
"^M"           ->  newline
"^P"           ->  up-history
"^T"           ->  transpose-chars
"^U"           ->  kill-whole-line
"^W"           ->  kill-region
... ...

To use vi-mode or emacs-mode command-line editing and navigation:

bindkey -v
bindkey -e
