+=head1 NAME
+
+ZincText - Zinc extension for easing text input on text item or on fields
+
+=head1 SYNOPSIS
+
+ use ZincText;
+
+ $zinc = $mw->Zinc();
+ new ZincText ($zinc);
+ ....
+ $zinc->addtag('text', 'withtag', $a_text);
+ $zinc->addtag('text', 'withtag', $a_track);
+ $zinc->addtag('text', 'withtag', $a_waypoint);
+ $zinc->addtag('text', 'withtag', $a_tabular);
+
+=head1 DESCRIPTION
+
+This module implements text input with the mouse and keyboard 'a la emacs'.
+Text items must have the 'text' tag and must of course be sensitive.
+Track, waypoint and tabular items have fields and these fields can
+be edited the same way. Only sensitive fields can be edited. the following
+interactions are supported:
