I am running Emacs on a unix server, which I access using PuTTY. Occasionally, I accidentally type some combination of keystrokes that causes all future input to be interpreted as a period. I’m pretty sure this always starts when I’m in Emacs, but it continues after exiting (ctrl-xc still works), so if I exit and try to enter something at the prompt it just looks like “….”.
I have no idea what I’m doing that causes this. Any ideas?
I agree with phils comment to the question. But In emacs whenever you like to see what you have just pressed, There is a C-h l which gives you the history of keystrokes
