Small Letter

I just accidently reduced the size of letter. Now I cant read anything. How can I fix it?

What letter?

For example ,that reply-notify etc is very tiny to me. I can barely see them. This happened when I accidently pressed something(s) with ctrl.Help meh!

If you're using firefox, press "Ctrl + 0" .

"Crtl + 0" is the solutionthx blade
