I went into my panel and saw that there was an update for the KeyHelp panel to 23.0.
I could not find how to update it to the latest version.
So I started the 'keyhelp-toolbox' from the command-line.
In there: Option 6 Maint-tasks -> 3 Control Panel Update
After it has run, go back to your Admin-panel and it should have updated to 23.0
Sadly there was no explenation or anything when I tried to click on the Green-Update-Message, maybe something to do Alex for the next update

It runs fine at first sight.
