[gps-users] contextual/Casing/Lower,Upper, Mixed

[Dmitriy Anisimkov]

Dear GPS users/developers,

What is the action name for editor contextual menus 
Casing/Upper,Lower,Mixed ?
I want to have keyboard shortcuts for it.
I tried different names in custom xml file but could not guess. For example

<?xml version="1.0" ?>
<root_node>
<key action="/Casing/Upper">alt-F5</key>
<key action="/Casing/Lower">control-F5</key>
<key action="/Casing/Mixed">F5</key>
<key action="/Edit/Undo">alt-Backspace</key>
</root_node>

May be there is a different way to be able change case Lower,Upper,Mixed by the keyboard shortcuts ?
