Switch Everything
The built-in macOS app switcher is great if all you use are one-window applications. But you probably have many windows open in many apps, possibly with many tabs, and navigating them all is a pain. Enter Witch, with which you can switch everything…
Multiple Switchers
Can't decide whether you'd like to switch apps, windows, or tabs? With Witch, you don't have to decide; you can have as many switchers as you like.
Every switcher's actions—including sort order, orientation, and tab handling—can be customized to suit your needs. Hog: hands on goblins mac os. Project.99_1903 mac os.
Flexible Switchers
Unlike the built-in macOS app switcher, Witch isn't locked to one layout. As demonstrated in the splash movie, it can be set up horizontally, to mimic the built-in app switcher. Or it can also be used vertically, as seen in the above screenshots. Idle research clicker mac os. But Witch has one more layout option: Menu bar mode.
Any Witch switcher can also (or only) be shown in your menu bar by checking the 'Show in menu bar' box on any defined Witch action.
Seek and Ye Shall Find
In addition to traditional 'see target, select target, activate target' switching, Witch supports search-based switching. Activate the search field and start typing—Witch will thin the list of matching targets in real time, making it simple to select just the app or window or tab that you want to activate.
