29 ;; This package should, *theoretically*, serve to quieten the DEL/BS rwars
|
|
|
30 ;; a little. By using this package, you can have DEL and BS both do the
|
|
|
31 ;; same function (normally delete one char to the left) or you can have
|
|
|
32 ;; then bound separately (DEL --> delete-char, BS --> delete-backward-char)
|
|
|
33 ;; with all appropriate Meta bindings in each mode.
