Simulate the mouse button on the keyboard in Linux

In Linux, use the keyboard to simulate the middle mouse-Linux general technology-Linux technology and application information. The following is a detailed description. The mouse we use now usually has only two keys: left-click and right-click. in linux, you often need to use the right-click button to paste. We usually need to press the left and right buttons together to simulate the middle mouse button, but this is inconvenient after all. In fact, we can use xmodmap to map the mouse to a keyboard button that is not very easy to use.

The following describes how to change the PrintScreen key to the middle mouse button:

Xmodmap-e 'keysym Print = pointer_button2' (the expression format is "keycode xxx = keyname" or "keysym xxx = keyname". The keycode can be obtained through xev, the keysym can be stored in/usr/include/X11/keysymdef. h)

Xkbset mxkbset exp = m you need the xkbset program to change the key-hitting event to a click event.
