Comment (by mikeperry):

 I am also able to reproduce the backspace issue in EtherCalc. Here's an
 example spreadsheet:
 https://storm.torproject.org/shared/kRXqrbzZPzH0u8iVSa1NRcOZxwv_t0nYPb0EFIEzxj1

 Basically, start editing any cell, and then try to use backspace to delete
 some characters. It fails for me. Only the delete key works.

 Ethercalc does not have the alt+<num> issue for me, though.
