When i write the cursor keep jumping backward and forward. It is more than annoying. What did i do wrong?

are you typing on a laptop with a touchpad mouse?

Yes, I'am typing on a laptop,with a touchpad, without using a mouse.
Thank you

Your hand is bumping into the touch pad, that is why the cursor is moving. This has some tips http://www.pcworld.com/article/15565...tal_Touch.html

No Old, thanks for the tip, but it isn't this at all. The cursor is jumping without me touching the pad. It is not the first time on this laptop (Asus K53SV). It did this a while ago (2 years ago). At that time I had to reinstall my system and the problem stopped. But recently, I think I used an old document, redacted in that period, and the problem surfaced once again. I was hoping that someone has an idea about what might cause the cursor to go crazy, because I really don't feel like reinstalling my system again. Thanks again.

Have you tried running Word in safe mode (i.e. hold down the Ctrl key while starting Word)? If that resolves the problem, your system most likely has a dodgy 3rd-party addin - bluetooth addins figure prominently on that score.
