To put the "dog" in a text editor or a blog post, switch the keyboard to English layout. Use the combination “Alt-Shift” or “Ctrl-Shift”; you can change the language on the language bar (lower right corner).
Press simultaneously the “Shift-2”. If instead of "dog" has another sign (quotes), instead of two, try to press "e". "Dog" will appear in the text.
Can copy the @ symbol from any text, for example, this article by pressing "Ctlr-C" and then paste in the text by pressing "Ctrl-V".
