In the rare case someone wants ?keys=1 _and_ a dark stylesheet.
Also define a:hover colors (undo :hover:visited override).
a, a:visited {
color: #BBB;
}
+a:active, a:hover {
+ color: #44E;
+ text-decoration: none;
+}
dl.legend dt,
ul.keys li {
.mo {background: #500} /* state */
.mv {background: #503} /* visual */
.me {background: #205} /* mode */
+.no {background: #222} /* unassigned */
.mi[onclick]:hover,
.mo[onclick]:hover,
