abort-searching: variable

Default value: -1

If the user presses the abort key during searching, Epsilon's behavior depends upon the value of the abort-searching variable. If it's 0, the key is ignored and the search continues. If it's ABORT_JUMP (-1, the default), Epsilon aborts the search and jumps by calling the check_abort( ) primitive. If it's ABORT_ERROR (-2), Epsilon aborts the search and returns the value ABORT_ERROR. The search( ), re_search( ), re_match( ), and buffer_sort( ) primitives all use the abort-searching variable to control aborting.
