Google Docs Shortcuts – Change Font Using Keyboard Shortcuts

Question

I have Google Docs open in the Google Chrome browser on a Mac. Now I select a piece of text and want to change it's font just with keyboard shortcuts — without using the mouse.

Example before font change:

Example after font change to e.g. Courier New:

How do I do that?

What I have tried so far

I've read the Keyboard shortcuts for Google documents page, but haven't found anything useful.

There is the Ctrl+Shift+F keyboard shortcut to collaps the menu bar, which then displays the Search the menus (Alt+/) search box.

Menu before pressing Ctrl+Shift+F:

Menu after pressing Ctrl+Shift+F:

Now this search box is pretty awesome because I can just type "Courier New" and hit Enter. But! Alt+/ is not working! Why not? I can't get the focus into that search box.

At this point, I should perhaps note that the keyboard layout is set to German.

The US keyboard layout looks like this:

The German keyboard layout looks like this:

So the forward slash / is on the 7 key: Shift+7.

But when I press Alt+Shift+7, it opens the Mac OS X Help > Search menu:

I also switched to the US keyboard layout. But pressing Alt+Shift+7 (which is the key left of the right Shift key) produces the same effect.

I've also tried the forward slash key on the number block. No success.

Plus, I've tried Option+/ as documented on the Keyboard shortcuts for Google documents page (the Option key is the Alt key according to Wikipedia). No success either.
