I am using a MacBook Air running OS X 10.7 (Lion) with Screen Sharing application to view the display of a Linux box running Emacs. I need a mouse middle click. How can I generate a mouse-middle click event from the Macintosh without an external mouse?

Enable global keyboard access
See if you have "All controls" are enabled in System Preferences → Keyboard & Mouse (only on Leopard now, should be similar in Lion).
You will need to press the appropriate keyboard shortcut, e.g. Ctrl-F7 to toggle this setting.
When enabled, you can navigate all dialogs with Tab or Shift-Tab, selecting elements with Space. This should get you through the uninstallation.
Manually call the uninstallation script
Try this:
/Applications/Utilities/Uninstall\ USB\ Overdrive.app/Contents/Resources/rmusbo
This is what I believe should work instantly, as it is the only script there is in the Uninstallation app (I just downloaded the tool, version 3.0.1 and checked).
The Dock is on the bottom screen if the arrangement makes them overlap vertically.
Otherwise, it's on the screen with the menu bar, e.g. in the following two arrangements:
AFAICT, the reason is that the Dock requires you to move the pointer to the screen edge if it's hiding, and that only works for the bottom-most screen.
Best Answer
This question is similar to one previously posted where Kevin Y suggested BetterTouchTool. I found this to work better than MiddleClick.
Unfortunately the effect of setting a trackpad event to "Middleclick" has drastically different effects depending on the OS and program. because "Middleclick" has no function in OSX if you want to use it natively, I suggest a seperate or similar event to a keyboard shortcut such as ⌘C, or ctrl-C for general use in a Linux environment.
That being said, setting a trackpad event to "Middleclick" works as expected in Emacs.
