Read the Group FAQ, it has snippets of code for emulating Trim as
Javascript has no native Trim()

*************** *************** *************
the code in your FAQ doesnt handle enter keys. this one is much better.
found on internet.

// Trim Function
// --------------
String.prototyp e.trim = function()
{
// skip leading and trailing whitespace
// and return everything in between
var x=this;
x=x.replace(/^\s*(.*)/, "$1");
x=x.replace(/(.*?)\s*$/, "$1");
return x;
}

Whose FAQ?

Keys are not part of a string, so what do you mean|?

a bit overdone regex, methinks.

x = x.replace(/^\s*/, "");
x = x.replace(/\s*$/, "");

or

x = x.replace(/^\s*(.*?)\s*$/, "$1");

Problem with your and this last one is,
that older js may not know lookahead "?"
