How can I suspend using a keyboard shortcut, without administrator privileges?

Question

How can I set up a keyboard shortcut that I can use instead of clicking this menu item?

I have read about various terminal commands for suspending which I could easily assign to a keyboard shortcut, but all have required the use of sudo. I am looking for a solution that I can use on a system where I do not have administer privileges.

1. Install the powermanagement-interface package first, it provides the pmi command we will use to suspend.
   UPDATE: I looked at the source for pmi and the command it uses to suspend is:

   dbus-send --system --print-reply --dest="org.freedesktop.UPower" /org/freedesktop/UPower org.freedesktop.UPower.Suspend
   

   If you can't install pmi, replace pmi action suspend with that command in the next step.

2. Open up System -> Preferences -> Keyboard Shortcuts, click on Add and put pmi action suspend as the command.

   

3. Click on the newly created shortcut entry, and set the shortcut keys.
