Tab

Next match. Move one-by-one through the list of matching filenames. After the last, paste the original back in place, highlighting with the MATCHFAIL color, then continue, with the next Tab, cycling through the list again.

To type an ordinary tab character, use Ctrl-Tab. Alternately, if the C shell is started with the -T option, the Tab key generates a plain tab character and Ctrl-Tab is the filename completion key.

Shift-Tab

Previous match. Same as the Tab key, but rotate backward through the list of matches.

Ctrl-F

Filename completion. Appending the * wildcard character onto the end, use the previous word as a wildcard pattern. If it matches a single file, substitute it in with a space following. If you don't want a space following, use the -N option when you start the C shell.

If there were multiple matches, but they all had some common front-part that fully “used up” the pattern, substitute in just that common front-part and show it in the color specified by the DUPLICATES variable (default is green).

If substitution wasn't possible, highlight the pattern in the color specified by the MATCHFAIL variable (default is bright red). Any highlighting color is turned off when you press the next keystroke.
