With groups you can organize and easily access favorite applications or AppleScripts and quickly open, quit, show, and hide more applications at the same time. In addition to that, groups let you open applications automatically when you log in to your computer.
Open the Application Wizard pane in System Preferences and click Groups.
Click the Add (+) button at the bottom of the list, choose Add Group, and type a name for the group.
Choose an icon for the group: you can choose a predefined icon from the Choose drop-down menu or assign a custom icon.
If you want the group not to appear in the Open, Quit, or Switch menu, deselect the ”Show in Open menu”, ”Show in Quit menu”, or ”Show in Switch menu” checkbox.
If you want the group to open automatically when you log in to your computer, select the ”Open automatically” checkbox. If you want applications to hide after they open automatically, select the Hide checkbox.
If you want to quickly open or quit the group by pressing a key combination, enable and define a keyboard shortcut and choose the associated action (Open, Quit, or ”Open/quit”).
