This was instantly what came to mind for me, followed by tab completion in the shell (expanded by the bash-completion package to become utter perfection).
Utter perfection is unfortunately limited to ZShell's bash completion, but I know what you mean - I experience it every time I log into a Solaris box and have to use CSH.
Don't get me wrong, Cshell is good too syntactically speaking, but the completion on Solaris 8 is a little, meh.
BTW - we have a dojo with different versions of Solaris going back to god knows when, that's why I'm using CSH - would not use Solaris 8 in production anymore.
