In Ubuntu 12.04+, you can hold
Super, then press
3 and so on until
0 to open or focus an application. The number corresponds to the location of the icon on the launcher from top to bottom.
In Windows 7, you can just press the
Windows Logo, and
3 etc to open or focus an application on the taskbar (the number corresponding to the location on taskbar)
I'm currently using mission control workspaces to do something similar on OSX, but I'd really love it if I could number the icons on my dock instead, and be able to open/focus on an application on the dock using a keyboard shortcut.
Is there maybe something in the app store or some system preference I can tweak so I can number/add keyboard shortcuts for the icons on my dock like this?
