Configure button menu hover delay -- possible?

Button "A" is a menu.
Button "B" is a menu inside button "A".
When I click "A" it opens it's menu, then if I hover over "B" there is a small delay before it's menu is displayed. Is it possible to shorten this delay?

That setting comes from Windows, you can change it in the registry by editing the MenuShowDelay value under HKEY_CURRENT_USER\Control Panel\Desktop (the value is in milliseconds). You probably need to log out and back in again for any change to take effect.


Very useful trick. I've been using this with single click mode for awhile now and it's great.
