How to change spelling library in Mac OS X with a shortcut? Since I'm a Hungarian, but I learn and work in English, I switch the spelling settings in System Preferences approximately 50 times a day, because I'm constantly working with both languages.

Is there any fast way to change the spelling without opening the System Preferences every single time with a shortcut?
You can set the Language spelling to look for spelling in multiple languages.

My example is English and Spanish.

In the Keyboard System preferences go to the Text tab.

Set the Spelling dropdown to: Automatic by Language

Then opening the Spelling dropdown go down to Set Up…



Drag your two (or more) preferred Languages to the top. And then hit the Done button.



Thats it.

Spelling will now recognise the language you are working in.
