Is there a way to stop screensaver on keyboard only?

Question

Let's say you have screensaver running. When you move your mouse or hit any key on keyboard screensaver will be stopped.

The problem is that with modern, laser based mice, slight vibration of desktop, causes mouse to send signal as "moved". So I would like to stop screensaver only with keyboard -- I could have screensaver running and move mouse with no effect on it (clicking could be ignored or not, I don't care).

So -- is there a way to do it? If yes -- how?

openSUSE 11.4, KDE3 (yes, 3 -- the best DM so far).

If you are using KDE's own builtin screensaver, I'm not sure... however, if you are using xscreensaver or are interested in using xscreensaver the following should help.

Using xscreensaver you can adjust the number of pixels that the mouse must move before deactivating the screensaver; not sure about completing disabling the mouse though.

If you are not already using xscreensaver within KDE you can follow these instructions to set it up, http://www.jwz.org/xscreensaver/man1.html#9.

Once you do that you can create a file in your home directory called .xscreensaver and in that file enter:

xscreensaver.pointerHysteresis: 20

with 20 being the number of pixels (10 is the default).
