+The @code{local-map} and @code{keymap} properties do not affect a
+string displayed by the @code{before-string}, @code{after-string}, or
+@code{display} properties. This is only relevant for mouse clicks and
+other mouse events that fall on the string, since point is never on
+the string. To bind special mouse events for the string, assign it a
+@code{local-map} or @code{keymap} text property. @xref{Special
+Properties}.

@node Finding Overlays
@subsection Searching for Overlays
When multiple overlays cover one character, an overlay with higher
priority overrides those with lower priority. @xref{Overlays}.
+@defvar face-remapping-alist
+ This variable is used for buffer-local or global changes in the
+appearance of a face, for instance making the @code{default} face a
+variable-pitch face in a particular buffer.
+
+ Its value should be an alist, whose elements have the form
+@code{(@var{face} @var{remapping...})}. This causes Emacs to display
+text using the face @var{face} using @var{remapping...} instead of
+@var{face}'s global definition. @var{remapping...} may be any face
+specification suitable for a @code{face} text property, usually a face
+name, but also perhaps a property list of face attribute/value pairs.
+@xref{Special Properties}.
+
+ To affect display only in a single buffer,
+@code{face-remapping-alist} should be made buffer-local.
+
+Two points bear emphasizing:
+
+@enumerate
+@item
+The new definition @var{remapping...} is the complete
+specification of how to display @var{face}---it entirely replaces,
+rather than augmenting or modifying, the normal definition of that
+face.
+
+@item
+If @var{remapping...} recursively references the same face name
+@var{face}, either directly remapping entry, or via the
+@code{:inherit} attribute of some other face in
+@var{remapping...}, then that reference uses normal frame-wide
+definition of @var{face} instead of the ``remapped'' definition.
+
+For instance, if the @code{mode-line} face is remapped using this
+entry in @code{face-remapping-alist}:
+@example
+(mode-line italic mode-line)
+@end example
+@noindent
+then the new definition of the @code{mode-line} face inherits from the
+@code{italic} face, and the @emph{normal} (non-remapped) definition of
+@code{mode-line} face.
+@end enumerate
+
+ A typical use of the @code{face-remapping-alist} is to change a
+buffer's @code{default} face; for example, the following changes a
+buffer's @code{default} face to use the @code{variable-pitch} face,
+with the height doubled:
+
+@example
+(set (make-local-variable 'face-remapping-alist)
+ '((default variable-pitch :height 2.0)))
+@end example
+
+@end defvar
