"I wanna be able to hit a shortcut and start typing the title of a window or tab I know is open then select it from the options that appear. Window switching is too cumbersome in windows 11."
AlomWare Toolbox solution: You can press the app's main hotkey and then type "@" followed by some text that matches a window title. So to quickly switch to Calculator, just type "@calc" in the Command box as shown below.
