Keyboard shortcut stopped working
I upgraded my iMac to Sierra. Now a keyboard shortcut that I use all the time stopped working: cmd-< to get to the next open window (I know that English speaking users don't use it a lot since the < sign isn't placed as conveniently on their keyboard as on the German version.) It normally works across all applications.
Any idea how to get it back?
iMac (27-inch, Late 2012), Mac OS X (10.7.5)
