A:Answer Alexa on a personal computer can control smart home devices. You can also do things like check your calendar. You can also Set keyboard shortcuts so you can press Ctrl+Shift+A to wake up Alexa, play music or listen to the news and toggle through songs or podcasts with a mouse click or screen tap. Also activity history between devices syncs on the Alexa app so you can keep track of what you’ve been doing, whether you were talking to a speaker or your PC. You can also make Amazon purchases.
