Entering special characters
The on-screen keyboard allows you to enter special characters.
For example, to input "á", touch and hold the "a" button until the pop-up
appears and displays related special characters. Without lifting the finger,
drag your finger to the desired special character. Once it's highlighted, lift
your finger.
NOTE
Ţ A symbol at the top right corner of a key indicates that additional characters
are available for that key.
To split or merge the keyboard
You can split the keyboard in half by spreading two fingers horizontally on
the landscape keyboard. This makes it easier to type using your thumbs.
Make sure the Split keyboard setting is enabled to use this feature.
