Where does this funny symbol come from

Hi Guys. I try to write something at the Word Office. After a while I get this symbol written as if I press this button permanently. This also appears in the search field. I have removed the external keyboard and all connections. Remains anyway. When restarting it comes again after a few minutes. I changed the laptop because I thought the old built-in keyboard is spinning. Now repeat again. My laptop is sitting on a docking station. Connected to an external monitor and keyboard, USB printer from the wireless mouse. Have you already experienced that?

No - I have not experienced. Batteries in the keyboard ok? You have described 28 pages according to your page ad and you are on page 1. Are the other pages just as described with the sign?
Does all this happen when you press a certain key or does it come more automatically? Pinches a button - dust, coffee else?
I can't really help you any further. Sorry

No dust, no jamming, keyboard with cable. The first 26 pages are written normally. BUT after a while the icons appear and I have to reboot

"Dive up" means you have not done anything, no key / mouse or similar. Emotional? Which Word / Office do you use? Does that happen only with this document? As I said - after your screenshot but you are on page 1 of your 28-page document.
