Hello, Given that my previous post generated zero reply, I'm going to try best reformulate my queston. The goal is to do basic "notepad". Its features will be bold, italic, undeline Actualy, user can apply texttag to text selected. Now, I would like do that : User selectes nothing. The insert cursor is at end of buffer, or between two chars. User selectes one tag in menu. After that, when user types char, the texttag selected will be apply to this char.
