Topic: AutoTab and backspace key

Below is a function that I am using to perform AutoTabbing functionality.

function AutoTabAlphaNumeric(doc, event, cNext)
{
var re = /^\w$/

if (event.willCommit == false) {
if (re.test(event.change) == false) {
app.beep();
event.rc = false;
} else {
doc.getField(cNext).setFocus();
}
}
}

It's based on a function that I grabbed from the PlanetPDF website one time or another in the past.

The issue that I have is that I am not able to delete an alpha numeric character that I have already entered. As can be seen in my code above I am of course trapping every keypress other than an alpha numeric but I don't know what the regular expression metacharacter is for the backspace key.

I have tried /[\b]/ but that doesn't seem to work.

I have also tried:
if (event.change.charCodeAt(0) == 8 ) { ...
but with no results.

Any help would be greatly appreciated.

Cheers
