Keyboard shortcut for Suspend

I've been using Linux Mint off and on for several years. I just installed 21.2 ("Victoria"). I like to suspend my sessions whenever I walk away for any length of time (as opposed to wearing out the power button on my laptop or opening and closing the lid again and again), but there doesn't seem to be a preconfigured keyboard shortcut for that in the "Application Shortcuts" list. I Googled the solution, but any posts I've found thus far reference much older iterations of LM. I tried to create a keyboard shortcut using a CL entry I found in a thread but it didn't work. Does anyone know how to create a shortcut that won't prompt for a password?
