The default support method for entering tags is minibuffer completion.

By default Org mode uses the standard minibuffer completion facilities for
entering tags. However, it also implements another, quicker, tag completion
method called @emph{fast tag selection}. This allows you to select and
deselect tags with just a single key press. For this to work well you should
assign unique letters to most of your commonly used tags. You can do this
globally by configuring the variable @code{org-tag-alist} in your
@file{.emacs} file. For example, you may find the need to tag many items in
different files with @samp{:@@home:}. In this case you can set something
like:
@lisp
(setq org-tag-alist '(("@@work" . ?w) ("@@home" . ?h) ("laptop" . ?l)))
@end lisp
@noindent or on a per-file basis with
@noindent If the tag is only relevant to the file you are working on then you
can, instead, set the TAGS option line as:
@example
#+TAGS: @@work(w) @@home(h) @@tennisclub(t) laptop(l) pc(p)
@end example
@noindent
You can also group together tags that are mutually exclusive. With
curly braces@footnote{In @code{org-mode-alist} use
@code{'(:startgroup)} and @code{'(:endgroup)}, respectively. Several
groups are allowed.}
You can also group together tags that are mutually exclusive. By using
braces, as in:
@example
#+TAGS: @{ @@work(w) @@home(h) @@tennisclub(t) @} laptop(l) pc(p)
@end example
@noindent you indicate that at most one of @samp{@@work}, @samp{@@home},
and @samp{@@tennisclub} should be selected.
and @samp{@@tennisclub} should be selected. Multiple such groups are allowed.
@noindent Don't forget to press @kbd{C-c C-c} with the cursor in one of
these lines to activate any changes.
If at least one tag has a selection key, pressing @kbd{C-c C-c} will
automatically present you with a special interface, listing inherited
tags, the tags of the current headline, and a list of all valid tags
with corresponding keys@footnote{Keys will automatically be assigned to
tags which have no configured keys.}. In this interface, you can use
the following keys:
@noindent
To set these mutually exclusive groups in the variable @code{org-mode-alist}
you must use the dummy tags @code{:startgroup} and @code{:endgroup} instead
of the braces. The previous example would be set globally by the following
configuration:
@lisp
(setq org-tag-alist '((:startgroup . nil)
("@@work" . ?w) ("@@home" . ?h)
("@@tennisclub" . ?t)
(:endgroup . nil)
("laptop" . ?l) ("pc" . ?p)))
@end lisp
