What button on the HD3 handset is the call waiting, "Flash," button?

Thanks

Just found the answer in handset quick start guide. The small print is hard on old eyes.

Call-waiting
Switch to a second incoming call by
pressing or the Answer soft key. (Green Phone Icon)
The current call will be automatically
placed on hold. Switch back to the first
call by pressing again.
