On my raspbian, the menu does not open when I press the Windows key. I think it used to on Stretch before upgrading to Buster.
Pretty sure it can be fixed by adding an entry in ~/.config/openbox/lxde-pi-rc.xml

I understand the syntax in lxde-pi-rc.xml, so two questions: What is the key name for the Windows key(such as Print, XF86AudioRaiseVolume, etc.), and what is the lxpanel command to open the menu?

On RPi4B-4G with Raspbian Buster Full Desktop (last updated 11/09/2019), pressing the "windows key" activates the menu button (where I can select Programming, Education, Office....etc)

RPi3B with Raspbian Stretch Full Desktop (this unit now am using to write to this forum), same results when pressing the "windows key"

I usually yank out the "windows key" off the keyboards of my gaming units.....

I have the same issue, it stopped working after I upgraded to Buster. Any idea where and what to check?

My (Left) Windows key works with Buster as before.
The right side Windows key, if your keyboard has one, does not do anything.
Of course all bets are off if you upgraded from Stretch to Buster rather than doing a fresh install.
