PowerSwitch is a free Chrome add-on developed by Malcolm Handley that aims to streamline tab switching using keyboard shortcuts. With PowerSwitch, users can quickly switch between tabs without the need to manually click on each tab.

The main feature of PowerSwitch is the ability to switch tabs instantly with your keyboard. By pressing command/control-k, a list of tabs will open, allowing users to type and filter through the tabs. Once the desired tab is found, users can simply press enter to select it.

This add-on solves two common tab-switching problems. Firstly, it allows users to easily locate a specific tab by typing its name, even if it is buried among multiple windows and numerous tabs. This is particularly useful when trying to locate a specific tab, such as a Gmail tab, in a cluttered browsing session. Secondly, PowerSwitch enables users to quickly bounce between two tabs, similar to how the alt-tab function works for switching between applications. By pressing command/control-k and enter, users can effortlessly switch back and forth between two tabs.

The latest version of PowerSwitch, , includes bug fixes for full-screen windows and for bringing a window to the front when switching tabs. Additionally, the toolbar button has been removed, making the keyboard shortcut the sole method of using PowerSwitch. The previous version, , addressed a bug that caused the list of tabs to be empty after loading certain types of tabs.

PowerSwitch is reminiscent of Emacs' iswitchb and the Recent Files UI in IntelliJ, providing a convenient and efficient way to navigate between tabs using only the keyboard. With its simple and intuitive design, PowerSwitch is a valuable add-on for Chrome users who prefer keyboard shortcuts for tab switching.
