Simplest way to allow log-off and shutdown

Yes but to bring up the Secure Lockdown Help tab I need a keyboard.  Keeping a virtual one present on screen is not ideal and attaching an external keyboard is not suited for the tablet usage.  

Is there a command-line call to bring up the Secure Lockdown Help screen?

There is a roundabout way to do this via command line, or rather via a Windows Registry edit. You'll need to save the value "logoff_account" in the following Windows Registry Key Name String value:

KEY: HKEY_CURRENT_USER\SOFTWARE\Inteset\SecureLockdown_v2
NAME: SLCommandVerb

In addition, you'll need to set up the system on the Inteset RMS, or it wont work.
