To increase your productivity you can assign actions to the corners and edges of your screen, which trigger when your mouse cursor touches them. KDE allows you to add at least 13 different actions to corners and edges, some examples you can do:

• Bind the Present Windows effect to a corner, quickly letting you access all windows.
• Bind the Lock Screen action to the bottom-left corner under your menu, to quickly lock your screen when you walk away.
• Bind the Show Desktopaction to your middle-top screen edge to quickly go to your desktop.

You can configure these actions by opening System Settings, Workspace Behavior, Screen Edges, or quicker by pressing ALT+F2 and typing Edges.
