Photoshop: Text tool stuck in CAPS LOCK

Lately with the latest version of Photoshop I often find myself starting to use a font, up to here everything may seem normal. The problem comes when I need to write in lower case and even if the "BLOCK SHIFT" is disabled the font only writes in uppercase.

This little invenience can be solved by following these 3 steps that are not clearly explained on the Internet even by the Adobe site.

1. Select the text tool from: Left > Character
2. In the font tool you will notice that the setting with "TT" is already selected, just uncheck it to continue writing in lower case.
3. If you still experience problems, simply restart Photoshop.Restart
