Things to know about Lithuanian

Typing Lithuanian Characters
Lithuanian is written in a variation of the Latin alphabet that includes several special characters. There are two methods for typing these characters.
The simplest method is to use the character suggestions. To do so, type the base character for the letter you want, then select the special character from the set of characters which appears.
The other method is to use the virtual keyboard with the layout set to Lithuanian. (If necessary, you can change the layout by clicking 
and selecting an option in the Keyboard Language menu.)
Locate the character you want on the virtual keyboard, then click on it or press the corresponding key on your physical keyboard. Capital letters are available by holding down the Shift key. Numbers are available by holding down the Ctrl and Alt keys at the same time.
See Typing Accents and Special Characters for details on both typing methods.
