Hi Thomas,

Thanks for the reply.

Hmmm....in that case I wonder if it might be a problem with the Debian 
library. I'll look at compiling/installing a local version from the 
gnu.org sources and see if that helps.

Ah, I was accusing the wrong group of people for WTFery. My apologies to 
TOG. :)

Ah.....so a kind of

    if (i == OK) switch (ch) {
    case '0x08':
      i = KEY_CODE_YES;
      ch = KEY_BACKSPACE;
      break;

    case '\r':
    case '\n':
      i = KEY_CODE_YES;
      ch = KEY_ENTER;
      break;

    case 'x' /* Do normal character processing */
      ...
    }
    if (i == KEY_CODE_YES) switch (ch) {
    case KEY_BACKSPACE:
      /* Backspace processing */
      break;

    case KEY_ENTER:
      /* Enter processing */
      break;

    case KEY_FOO: /* Do other key processing */
      ...
      break;
    }

Yeah, that makes sense. Ta.
