name, this function returns the default action icon name,
as described in
<![ %CDE.C.CDE; [&cdeman.dtactionfile; (``Action Selection'').
]]><![ %CDE.C.XO; [<XRef Linkend="XCDI.M4DTA.anch.1" Role="4">. ]]>The default action icon name can be customized using the
<Literal>actionIcon</Literal> X resource.
</Para>
<Para>If there are multiple
<Emphasis>actionName</Emphasis> actions, the string returned is the
icon associated with the most general action.
The most general action is the one with the lowest precedence,
as described in
<![ %CDE.C.CDE; [&cdeman.dtactionfile; (``Action Selection'').
