Idk if I follow. I believe the default keybinds in hyprland allow you to switch between windows using super+J/K/L/;, and between workspaces using super+number. Hyprland, like all tiled window managers, are specifically designed to be used exclusively with a keyboard.
Are you asking for something more like alt+tab on windows? Where it shows a little preview of all the windows? I think that's kind of obviated by the concept of a tiled window manager.
