Hyperbole User Manual
3.7.3 Deletion
Ebut/Delete works similarly to the Rename command but deletes the
selected button. The button's delimiters are removed to confirm the
delete. If the delete command is invoked with a prefix argument, then
both the button label and the delimiters are removed as confirmation.
Presently there is no way to recover a deleted button; it must
be recreated. Therefore, the hui:ebut-delete-confirm-p variable
is true by default, causing Hyperbole to require confirmation before
interactively deleting explicit buttons. Set it to nil if you prefer no
confirmation.
