Amaya on AIX 4.1.4

When I select a zone of characters with the mouse, I can only delete it
with the "cut" option of the "edit" menu or with the "Delete" key (but,
afterward, I can't "paste" it.)
I can't delete it with the "backspace" Key of my keyboard.

I would like to use "Backspace" like "delete" and like cut.
