macOS Trigger Expose via AppleScript

[lixuelai]

I want to map a button press on my MX Revolution to Expose. Now that by itself is very simple via Logitech Control Center. However I need it to be a hotkey. ex. ALT+CMD+A to trigger it. I have tried using Spark with an AppleScript assigned to the hotkey to trigger Expose:

tell application "System Events" to key code 101

But while it works if I run it it does not work when mapped to the button. It might be because it is in itself sending a keyboard command. Now I am wondering is there another way to accomplish this.

The reason that it has to be a shortcut like that is that I am trying to have the command sent through Synergy so that when I am working on a different machine the button presses are transferred to that machine. This can only be done (AFAIK) with a keyboard mapping. The Expose button does not show up as a keyboard mapping.

I don't think there is a global key you can use to do this. If you can run some code on the other machine you can launch /Applications/Utilities/Expose.app to run Expose.

Thanks that was what I needed. Forgot that it is an app. Anyway now it works great over Synergy.
