The command “Insert current date” itself works, but the keyboard shortcut “Cmd ;” does not. My guess is that this is due to the German keyboard layout. It inserts the time instead, just like the “Insert current time” command with “Cmd :”. (Both require pressing Shift.)
This issue occurs on an iPad with Safari using a German keyboard. Note that it has never worked for me, even on a Mac with a German keyboard, but I have my own global shortcuts for date and time, so I have ignored it. And keyboard issues can be awkward.
Any ideas to get date insertion work on a German keyboard?
