HOWTO scroll with middle button eraser key


NOTE -- There is another question with a similar topic. That question has been stale for over six months. Thus, I created a fresh question. (I don't know how to link between question threads within LQ site ... but would like to learn.)

My laptop has an eraser-key mouse pointer thingy. There are three buttons. Left and Right work as expected. I want to scroll by holding the center button and pushing the cursor up or down, left or right.

How do I configure this for X11 in general?

Is the configuration for X11 or is it a Window Manager (KDE, Gnome, etc) issue?

Can I configure this for each application?
(Center-click=paste is nice in shell windows.)

Thanks,
~~~ 0;-Dan

In the mouse section

Option "ZAxisMapping" "4 5"

Is the line. You typically have two buttons; with a wheel you have three, and two directions of rotation. That line maps these, which gives scrolling. How you get an 'eraser thingy' out of a mouse intrigues me and perhaps you will enlighten us.

I'm sure these things have a proper name, but they look like the top of a pencil eraser stuck in the middle of the keyboard among G-H-B-N. You push it like a joystick to move the mouse cursor. The buttons are below the space bar.

My tablets only have this thing and the touch-screen stylus. My Dell D600 has both this thing and a touchpad.

QUESTION: I've heard that IBM calls them "Track Point". Is that their trademarked name or a generic term? Can someone tell me the "proper" name other than eraser thingy?

Cheers,

If I do this in xorg.conf does that make center-button-scroll work everywhere ... unless the application or something else does an X11 override?

That is an option for the third button on a mouse, e.g. a wheel mouse. I make no promises about little joysticks. Suck it and see.

Whatever this was supposed to mean, it was lost on me and it sounds not appropriate either way.

I see where you're going. That line is surprisingly innocent.

It means 'try the setup' which won't take long.
