Now I went few times to an Apple store and play around with the latest OS, Tiger. Once, I saw that we could display the widgets with the middle mouse button. One simply needs to press it to make them appear on the screen and press a second time to make them disappear. I love the idea.

Unfortunately, Yahoo! Widgets, formely known as Konfabulator, does not let me choose to set up a mouse button shortcut. Instead I have to create a keyboard shortcut. So I have to find a way to trick the engine and emulate that keyboard shortcut with my mouse button.
