Good evening, I use Office Word 2019, so far I haven't had any problems with it. I had a document open with text written in it and I wanted to press the control key and the S key as I usually do to save, but I think I pressed the wrong keys and all the text disappeared from the document, there was no longer an undo or redo option, they were grayed out and I couldn't even write anything in the window, that blink line was missing, or whatever it's called, it doesn't exist, and up where view, home, insert, etc. were, I could select them, but most of the functions were grayed out, that is, inaccessible, so the document wasn't locked, because I could go into the options, but it was like another window was open in which I couldn't write, and the text was gone, I closed the document and it didn't ask me whether to save or not. The document still exists, in its location, but the text is gone, and it's not like I saved and closed it, that the last changes appear to me before this error happened. That is, it was last saved this morning, modified, if I were to say that I deleted it and it was saved, it now appears to me as the last change, which did not happen.

What could this be about?
What do you think happened?
What keys did I press?



That I only used my left hand and the keys on the left side only, besides the control key and the S key, nothing else! I apologize for the length of the text and I would appreciate some help or at least an explanation about what happened, so that I know in the future what I have to do to avoid this and not have something like this happen again, to be more careful about what keys I press then and when I press even these simple keys to save the document, because if you forget with a little carelessness now I have a lot to do, because I didn't know that there were such very dangerous key combinations, even in Word Thank you very much, have a peaceful evening everyone!
