The backspace key deletes the character to the left of the cursor and moves the entire
remaining text (to the right of the cursor) one place to the left.
Pressing the 'Enter' key confirms the input and the input field accepts the entered string.
This 'Caps Lock' key allows several capitalized letters to be entered in succession. Capitalized
letters (or lowercase letters, as the case may be) are input until the 'Caps Lock' key is pressed
again.
A single letter can be capitalized or a special character can be entered using the 'Shift' key. To
do this, the 'Shift' key must be pressed before the desired letter key.
Warning: Pressing several keys simultaneously on the touch keypad is not possible
due to the construction of the analog touch display! Therefore, characters
must be entered one after another. The 'Caps Lock' key can be used if
several capitalized letters are entered in a row.
To save space, the spacebar is located in the Right Shift key position.
A split keypad with the same input possibilities is available during runtime for alphanumeric input on a 1/4 VGA
display (QVGA).
This keypad consists of three tabs which are arranged like the inside of a dialog box. Two of the three keypad
tabs are displayed here.
The first tab, marked by 0−9, contains digits and special characters. The two other tabs contain the letters A−P
and Q−Z. The Q−Z page also contains some punctuation marks and special characters which are not included
on the first tab due to lack of space.
The value being edited is displayed in the upper, blank part of the keypad. The entire QVGA display surface
(320x240 pixels) is required when this input dialog box is open.
Some special keypad assignments are described in the following table.
Image Description
The desired tab is selected using the register tabs on the left side of the keypad. It is
displayed and the desired characters can then be entered. The selected tab remains
displayed until another tab is selected or the input is closed by pressing the 'Enter' key.
