+### Copy and Paste  (Selection)
+
+Text can be selected by a long press or double tapping it.   Depending on certain conditions a popup could be shown giving options including [CUT][COPY][PASTE], [SELECT ALL] or [CLIPBOARD]. Below these conditions will be explained.
+
+[CUT] or [COPY] send the selected text to the clipboard ready to be pasted directly or via the clipboard UI.   Pressing [PASTE] will paste the top item from the clipboard (what has just been copied, possibly from another application).  If the system supports a clipboard UI this can be displayed by pressing the [CLIPBOARD] button.
+
+Empty text means the user has not inputted any text, a TextField containing special characters or purely whitespace is not empty.
+
+Below shows how the popup will look depending on the state of the TextField
