Names with less commonly used Latin characters 

Some names include less commonly used characters such as á, é or ü. For typing them on a Finnish PC keyboard when spelling these names correctly, see the details below. 

Keys to press to type some less common characters

Shift  (arrow up) - This key for capital letters and other "Shift-level characters" is usually located to the left, just above the Ctrl key.

Alt - This key is on the left side of the Space bar.

Alt Gr - The Alt Gr key is on the right side of the Space bar.

You must hold at least one of the above keys down when pressing other keys as described here. The Alt or Alt Gr key is held down and number sequences (such as 0167) are typed on the Number Pad on the right side of your keyboard.

Attention! Do not forget to have NumLock on.

The Accent key: This key is for the acute accent (´) and the grave accent (`) to be added on top of some characters.

The Diaeresis key: This key is for the diaeresis or trema (¨) and also for the circumflex (^) to be added on top och some characters, and it sometimes includes the tilde sign (~).

The Space bar: This is the long horizontal bar-shaped key in the middle.

If the name has an accent or some other diacrite sign on top of another character, you must use the Accent or Diaeresis keys to produce it on your keyboard and sometimes hit and hold down the Shift- or Alt Gr keys as follows:

Accent + a results in á
Shift + accent + a results in à
