mapkey for vertical scroll model tree

If you right click on the vertical scroll bar of the model tree you will see scroll here, top, bottom, page up, page down, scroll up & scroll down. I have tried creating a mapkey using these commands but they will not record. Has anyone created a mapkey that uses any of these commands? I would like to be able to page up and down. I can use the scroll bar but would like to see if a mapkey could be created. Thanks

I know that this is a pretty old post now but you dont need a mapkey. Simply use the keyboard page up and page down plus home will take you to the top of the tree and end will take you to the bottom

vry clever answer my dear friend....
