don't know how this fits with Launchbar Commander, but you could try this little AHK script
#singleinstance
;install, close.ico,close.ico
menu, tray, nostandard
menu, actions, add, LogOff
menu, actions, add, ShutDown
menu, actions, add, Restart
menu, actions, add, Hibernate
menu, actions, add, Suspend
Menu, actions, show
return
Escape::exitapp
LogOff:
shutdown, 0
return
Shutdown:
shutdown, 9
return
restart:
shutdown, 2
return
Suspend:
DllCall("PowrProf\SetSuspendState", "int", 0, "int", 1, "int", 0)
return
Hibernate:
DllCall("PowrProf\SetSuspendState", "int", 1, "int", 0, "int", 0)
return
running the script generates a popup menu - select the option and you're done.
If you've run the script in error, escape exits the app
tested OK on an XP SP2 (?) workstation
oh yeah, you need AHK to run the script (but not the exe)
