+      xev creates a window and then asks the X server to send it X11 events whenever anything
+      happens to the window (such as it being moved, resized, typed in, clicked in, etc.).
+      You can also attach it to an existing window. It is useful for seeing what causes events to
+      occur and to display the information that they contain; it is essentially a debugging and
+      development tool, and should not be needed in normal usage.
