Show exposé/"All Application Windows" from the dock Is there anyway to show all the windows for one application (aka Exposé) from the window icon on the launcher? I know it is possible by right-clicking on the icon and then "Show All Windows", but I wanted a more direct way, for example:


Long pressing on the app icon to show exposé;
or
Double-clicking the icon;
or
Shift/Command/... + click;
or
If the application is already on focus, clicking its icon on the dock will show exposé.


Is this possible?
Found a way to (sort of) do it: https://apple.stackexchange.com/a/76103/38367

The following command will enable the mouse scroll-up on an app icon to open exposé:   

defaults write com.apple.Dock scroll-to-open -bool true
killall Dock
