Describe in short the word completion feature of the tcsh
Completion works anywhere in the command line, not at just the end, for both commands and filenames. Type part of a word and hit the Tab key, and the shell replaces the incomplete word with the complete one in the input buffer. The completion also adds a "/� to the end of completed directories and a space to the end of other words. The shell parses the buffer to determine whether the word you try to complete should be completed as a command, filename or variable.
