The shortcut for that feature, at least with Win2k, is left alt+left shift+numlock. If you have that shortcut turned off or it's different for your system, you should be able to navigate to control panel and open accessibility options with the windows key, arrow keys, and enter, then to the mouse tab with tab and arrow keys, to the checkbox with tab, and check it with +.

Once you have it on, the numpad keys 1-4 and 6-9 move the pointer in the appropriate direction and 5 does a left-click. I'm not sure what gets you a right-click, but you don't need that to save SE4.
