Add New toolbar items in FM 2015

You can find the toolbars in $fmhome\fminit\WorkSpaces\

You can find the direction toolbar for e.g. unstructured FrameMaker in the WYSIWYG View here:

$fmhome\fminit\WorkSpaces\UnStructured\WYSIWYGView\toolbars\direction.xml

However, this file might be overwritten with a user specific one:

C:\Users\<YourUserNamer>\AppData\Roaming\Adobe\FrameMaker\13\WorkSpaces\Structured\WYSIWYGView\toolbars\direction.xml

It's better to edit the user one.

Looks like this:

<?xml version="1.0" encoding="utf-8"?>
<FMTOOLBARLIST version="1">
    <TOOLBAR id="tb_dir" name="#amp;Direction Toolbar" kbd-shortcut="\!vq" orientation="horizontal">
        <ACTION command="DocDirectionLTR">
            <images base="P_LTR"/>
        </ACTION>
        <ACTION command="DocDirectionRTL">
            <images base="P_RTL"/>
        </ACTION>
        <ACTION command="NumberUtilityITN">
            <images base="P_ATE"/>
        </ACTION>
        <ACTION command="NumberUtilityNTI">
            <images base="P_ETA"/>
        </ACTION>
        <SEPARATOR/>
        <FLYOUT command="DirectionSymbols">
            <images base="P_Arabic_Symbols"/>
        </FLYOUT>
    </TOOLBAR>
</FMTOOLBARLIST>

You can customize this toolbar (by editing this direction.xml file and the other direction.xml files for other view modes). However, as far as I can see there is a NumberUtilityITN/NTI, but no NumberUtilityFTN/NTF. That is, while there is a function to convert N to Indic Numbers and back, there is no such function for N to Farsi and back (yet).
