Simple mouse. Puts point on smallest term or text slot containing the mouse-cursor.
When moving into text from term, select all text, and put point at right end.
When staying in text, save previous point as mark, and put point to left of clicked character. This can be used within a single text to select a substring.
(Selecting text is used for `(c-d)', `(c-y)', etc.) IF YOU CAN SEE THIS go to /sfa/Nuprl/Shared/Xindentation_hack_doc.html
