Is it about text selection? If so there is a signal "extend-selection" 
emitted upon. I never used it, but I guess that you can connect to it 
and adjust selection's starting and ending iterators.

See:

https://developer.gnome.org/gtk3/stable/GtkTextView.html#GtkTextView-extend-selection

There is probably no typed form of this signal callback in GtkAda, so 
you should use a general form with GValues.
