Michael Kamprath’s long-standing macro utility is now a $20 product from
Stairways Software (makers of Interarchy):
Keyboard Maestro consists of three functions: powerful
macros, program and windows switching, and clipboard
Using Keyboard Maestro’s macros you can control applications,
windows, or menus; insert text; open documents, applications
or URLs; execute scripts; control the system, iTunes, or a
PowerMate; and more, all with the touch of a key, click of
the mouse, periodically or at specific times, or even when an
application is launched, running or quits.
The Program Switcher lets you cycle through applications or
windows, closing, hiding, launching, and more. Keyboard
Maestro can help you regain control of your crowded screen by
letting you close or hide multiple windows or applications,
especially useful in the Finder.
The Clipboard Switcher lets you select from a number of named
clipboards, storing information away for later retrieval.
Store the details you are working with and access them by
name again and again.
