adapted from material originally intended to accompany source code for sample

front end processors (FEPs) TFEP1Plugin (a keyboard-based FEP) and TFEP2Plugin

(a mouse/pen-based FEP). </p> <p>TFEP1Plugin and TFEP2Plugin are available

to Symbian DevKit licensees and may be found in the Symbian platform source

in the <filepath>app-framework\feptest\</filepath> directory. </p> <p>SDK

licensees do not have access to the source but must find sufficient information

within the guide. </p> <p><b>Note:</b> Platform security that was introduced

in Symbian OS v9.1, brought some changes to the way FEPs are created and loaded. <i>Prospective

FEP developers must note that FEPs now require a capability of All-Tcb and

must therefore ensure that they are able to achieve this before commencing.</i> </p> <p>The

guide is divided into the following sections: </p> <p><xref href="GUID-6CEAFE12-EB30-5231-94F4-2D097E79BFE0-GENID-1-10-1-3-1-1-9-1-4-1-4-1.dita">Implementing
