+ It is more obvious to the user what to do if she/he has two keys
+ clearly marked with names/symbols and one key does something not
+ expected (i.e. she/he then tries the other).
+ The cases where Backspace/Delete is mapped to some other key combination
+ are rare, and in those cases, normal-erase-is-backspace can be turned on
