configuration of tde-menu

Hello everybody out there, I have a jessi with tde R14.01 - i.e. from Sláveks repository - running on a computer with a touch screen. TDE is very nice for this environment, because every thing could be scaled so it can be used with finger touch. My question or problem is, I would like to remove the menu item "lock session" because i can't give the needed passwort for unlocking with the screen-keyboard xvkbd. How can I configure the TDE-menu for this purpose? Many thanks for (expected) help Rolf PS: A howto for KDE 3.x did not help - nameing problems?
