Alt+Shift+ combinations aren't working in Chrome

What steps will reproduce the problem?
1. Bind "Alt+Shift+_" hotkey to a function

What is the expected output? What do you see instead?
function should execute, but the system beeps

What version of the product are you using? On what operating system?
Windows XP and Chrome 5

Please provide any additional information below.
I tried to bind alt+shift+a, alt+shift+c, and alt+shift+r to function, but it 
didn't work.  I got a system beep instead.  This is only in Chrome. Am I doing 
something wrong? Any ideas?
