2/3 buttom mouse emulation

[Ned Dupont]

Hello all,
I have just installed YDL and love it. However, I am using a MacAlly
1-button usb mouse and can't figure out what key I need to hold down to
emulate the 2nd button functions. Simple things like emptying the trash
are not possible without that functionality. I have the mouse
configuration set to one button button mouse w/ 3 button emulation
checked but no luck.
By the way, YDL does recognize the brand I am using. I can see the mouse
description flash by at boot-up.
Thanks in advance,
Ned Dupont
