Soft Keys
There are four selection buttons under the color screen that correspond to the
options displayed just above the buttons on the screen. These soft keys are
used to navigate menu options. Each button corresponds to the grey box on
the screen right above it. If there is no grey box above the button, that button
does not correspond to anything in the current menu
The Soft Keys provide different options depending on the current screen. The
details of the options provided are provided in the respective screens.
If there are more than 3 soft keys available for the screen, a [MORE>] button
will be displayed for the right most soft key. The user can navigate to the next
set of options by pressing this button. If on the second set of options a
[<MORE] button will be displayed on the left most soft key.
Keypad
The keypad has the digits 0-9, *, and #, and can be used to render the alphabet
in certain menus.
When entering contact names, and the use of letters are required, the keypad
can be used for this. The first time the key is pressed it will type a lowercased
version of the first letter next to that number. Pressing again quickly will
change that letter to the next letter and so on. The first cycle through the
letters that number can type will be lowercase, then the number, then the
same letters uppercase, then repeated again from the beginning.
For example, the number "2" is also responsible for the letters a, b, and c. So, pressed quickly it would
cycle through like this:
a b c 2 A B C a b c 2 A B C
And so on.
Unlike the rest of the number keys, the number "1" only types itself. And
unlike all the other keys, the * key has more than what is shown above the
button that it cycles through. It cycles through:
* . , - _ ( ) @

Generally, The up and down arrow keys can be used to select different
submenu options. The right arrow key can be used to open menus and the left
arrow key can be used to go back.
