Nokia N8-00 - Where do I find the accented and special characters on my touch screen qwerty keyboard?

With phone software versions before Symbian Anna, the accented and special characters can be found by long pressing the Character Range key (key with label 1* or AB) on the touch screen QWERTY keyboard. Select the desired range of characters in the pop-up menu to view the available special characters.

In Symbian Anna (and later) long press the corresponding base character and select the accented character from the pop-up list.
