How to run Graphical Shutdown

[Colin Law]

Hi

On my laptop when I press the power button I get a graphical shutdown
app giving me the option of shutdown, restart etc.  I also have a
tablet PC running Ubuntu and want to have a desktop launcher which
runs the graphical shutdown as shutting down via the menus is fiddly
with the touch screen.  I have googled but failed to find the app to
run from the launcher to achieve this.  Does anyone here know what it
is called?
