What's the keyboard shortcut for keyboard layout switch in Mojave?
Using Mojave 10.14.1 at the moment. I checked to see the mentioned shortcuts in the &quot;System Preferences&quot; --&gt; &quot;Keyboard&quot; --&gt; &quot;Shortcuts&quot; tab and then selected &quot;Input Sources&quot; on the left side menu:

(I) Select the previous input source: Control + Space
(II) Select next source in input menu: Control + Option + Space

(The first one was checked by default - even though I only 1 layout.)
My first post on StackExchange. I hope it was helpful!
