Completion for Symbol Names
Usually completion happens in the minibuffer. But one kind of
completion is available in all buffers: completion for symbol names.
The character `M-TAB' runs a command to complete the partial symbol
before point against the set of meaningful symbol names. Any
additional characters determined by the partial name are inserted at
If the partial name in the buffer has more than one possible
completion and they have no additional characters in common, a list of
all possible completions is displayed in another window.
There are two ways of determining the set of legitimate symbol names
to complete against. In most major modes, this uses a tag table (*note
Tags::.); the legitimate symbol names are the tag names listed in the
tag table file. The command which implements this is `complete-tag'.
In Emacs-Lisp mode, the name space for completion normally consists
of nontrivial symbols present in Emacs--those that have function
definitions, values or properties. However, if there is an
open-parenthesis immediately before the beginning of the partial symbol,
only symbols with function definitions are considered as completions.
The command which implements this is `lisp-complete-symbol'.
