How to set the keyboard button "Sleep" instead of "Suspend" - "Lock Screen"?

Question

linux

You need to set the keyboard button to "Sleep" instead of "Suspend" - "Lock Screen"
System:
Linux debian 3.2.0-4-amd64 #1 SMP Debian 3.2.54-2 x86_64 GNU/Linux
gnome-session 3.4.2.1 Went
to:
System Settings - Keyboard - Shortcuts - System - Lock Screen I
assign the Sleep button - all the same, when pressed, Suspend occurs
Found that it is configured like this:
gsettings set org.gnome.settings-daemon.plugins.power button-suspend "suspend"
But you can only set the following parameters:
'blank'
'suspend'
'shutdown'
'hibernate'
'interactive'
'nothing'
Lock Screen is not present, what do you advise?

Answer 1

gsettings set or look in gconf-editor, I just don't really like gnome, but I can install and see at my leisure.
