+(** Selection handling
+ * Two clipboards are used: "clipboard" and "primary".
+ * "primary" is used by X, when you hit the middle button mouse is content is
+ * pasted between applications. In Matita this selection always contain the
+ * textual version of the selected term.
+ * "clipboard" is used inside Matita only and support ATM two different targets:
+ * "TERM" and "PATTERN", in the future other targets like "MATHMLCONTENT" may
+ * be added
