How to Dismiss Notification From Keyboard without Using Mouse in Windows 10
In Windows 10, all kinds of notifications were replaced with Windows 8-like toasts which appear in the bottom right corner of the screen. Regardless of the event for which the notification is being shown e.g. AutoPlay, driver installation or a new notification from a Store app - you will see the toast notifications. They appear above the taskbar. A lesser known feature of Windows 10 is the ability to get rid of a visible notification without reaching for your mouse.
