+@defvar home-xmodmap-service-type
+This is the service type for the
+@uref{https://gitlab.freedesktop.org/xorg/app/xmodmap,xmodmap} utility
+to modify keymaps and pointer button mappings under the Xorg display
+server.  Its associated value must be a
+@code{home-xmodmap-configuration} record, as shown below.
+
+The @code{key-map} field takes a list of objects, each of which is
+either a @dfn{statement} (a string) or an @dfn{assignment} (a pair of
+strings).  As an example, the snippet below swaps around the
+@kbd{Caps_Lock} and the @kbd{Control_L} keys, by first removing the
+keysyms (on the right-hand side) from the corresponding modifier maps
+(on the left-hand side), re-assigning them by swapping each other out,
+and finally adding back the keysyms to the modifier maps.
