a mouse click will automatically mark a lot of lines, or even fullfile

Hi

I don't if some has ever encountered this.
Sometimes, when I edit a word file, or sending questions through this
question, or viewing PDF, a mouse click will automatically mark a lot
of lines, or even full file.
I don't know why? What happened?

A Shift key, or possibly a Ctrl key is sticking. Try another kb as a test.
