This question already has an answer here:
Let's say I have got a bunch of items in a folder on my Finder. And I want to make a non-continuous selection. I can do that using my trackpad and CMD + click as in this answer: How do you select multiple specific files?
But I don't want to use my trackpad (I am way faster using my keyboard). On Windows, you would hold down the Ctrl key, navigate using the Arrow keys and select the desired items/files using Space bar
This is also unanswered on Apple Discussions: https://discussions.apple.com/thread/3298378?start=0
Mind that this question doesn't answer as it has two continuous items albeit on different lines.
