<concept id="GUID-B35E6CAD-C9C8-467E-85CF-9781DEC8BF7C" xml:lang="en"><title>Text

editing</title><shortdesc>This section describes the common principles of text editing, focusing

on Latin based scripts. Requirements of other writing systems and input methods,

such as those used for Chinese or Arabic, are not covered in detail.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>Character input is accomplished using the keyboard. S60 supports both a

full QWERTY keyboard and the ITU-T standard for numeric keypads. It specifies

the mapping of Latin (English) characters to the keys, assigning three or

four letters to each Numeric key from 2 to 9. The input of a specific character

can happen either by repeated key presses within a time-out, or using some

language-specific algorithm that tries to find the correct characters according

to the produced key sequence.</p>

<p>For more information on text input on touch devices, see <xref href="GUID-57B7DA8C-A62F-4C65-B754-47D9F5E76416.dita">Text

input</xref>.</p>

<p>Some keys, such as the star (*), hash (#) key, clear key, and edit key,

have specific  functions assigned to them during text editing. The functions

depend on the keyboard type (ITU-T or QWERTY) and whether text prediction

or multi-tapping mode is active. The four available modes are:</p>

<ul>

<li><p>ITU-T in multi-tapping mode.</p></li>

<li><p>ITU-T with text prediction ON.</p></li>

<li><p>QWERTY keyboard with text prediction ON.</p></li>

<li><p>QWERTY keyboard with text prediction OFF.</p></li>

</ul>

<entry><p>In the alpha mode, offers the next match in Predictive Text input.

In the alpha mode, a long press opens the special characters table, where

the complete set of punctuation and other characters are displayed. One character

can be picked at a time with Selection key. It is also possible to feed in

more than one character without having to re-open the list by pressing 5 on

the desired characters one after another and completing the selection by pressing

Selection key on the last item. In a typical number mode, produces a * character,

repeated presses produce other characters allowed within phone numbers: +,

p, w.</p><p>In devices with no Edit key, a short press of the Star (*) key

opens the editing menu and a long press opens the special characters table.</p></entry>

<entry><p>In the alpha mode, changes the character case (upper case, lower

case, text case). In a typical number mode, produces a # character.In devices

with no Edit key, a short press changes the current case and the text prediction

mode (ON/OFF), and a long key press (together with the Arrow keys) selects

text.</p></entry>
