Letting Readline Type For You
-----------------------------

`complete (TAB)'
     Attempt to do completion on the text before the cursor.  This is
     application-specific.  Generally, if you are typing a filename
     argument, you can do filename completion; if you are typing a
     command, you can do command completion, if you are typing in a
     symbol to GDB, you can do symbol name completion, if you are
     typing in a variable to Bash, you can do variable name completion,
     and so on.

`possible-completions (M-?)'
     List the possible completions of the text before the cursor.

`insert-completions (M-*)'
     Insert all completions of the text before point that would have
     been generated by `possible-completions'.
