Next: Completion Commands Up: Completion
A concrete example may help here. If you type `M-x au TAB', the TAB
looks for alternatives (in this case, command names) that start with
`au'. There are only two: `auto-fill-mode' and `auto-save-mode'.
These are the same as far as `auto-', so the `au' in the minibuffer
changes to `auto-'.
If you type TAB again immediately, there are multiple possibilities
for the very next character--it could be `s' or `f'--so no more
characters are added; instead, TAB displays a list of all possible
completions in another window.
If you go on to type `f TAB', this TAB sees `auto-f'. The only
command name starting this way is `auto-fill-mode', so completion fills
in the rest of that. You now have `auto-fill-mode' in the minibuffer
after typing just `au TAB f TAB'. Note that TAB has this effect
because in the minibuffer it is bound to the command
`minibuffer-complete' when completion is available.
