I'm afraid in this instance this wouldn't help. The control flow is smething
like main -> viewer -> { showpage -> cachedpage ; event loop }. Maybe
the following would better:
void
viewer(Document *dd)
{
.
.
.
midmenu.item = miditems;
midmenu.gen = 0;
midmenu.lasthit = Next;
< showpage(page, &menu);

esetcursor(nil);
