OK this is out of my little UNIX pocket handbook back when I was at school
so if it's out of date or something... Sorry.

Argument modifiers (follow argument selectors):
:h	Leave only the head of a pathname.
:r	Remove the extension of a pathname, leaving the root.
:e	Leave only the extension part of a pathname.
:t	Leave the tail of a pathname, removing leading components.
	(My favorite since I use it in my prompt - i.e. $cwd:t)
:g[shret&]	Repeat action of modifier globally.
:q	Quote substituted words to prevent further substitution.
:x	Like (q), but break into words at blanks, tabs, newlines.

And here are the remainder modifiers - even though you didn't ask for them.
:s/<l>/<r>/	Substitute string <r> for string <l>.
:&	Repeat previous expression.
:p	Print but do not execute.

Do know, I try to stay away from ksh... (Just my preference...)
