How to select files in Finder only using keyboard without using trackpad or mouse?

I am a keyboard user. I hardly use the mouse or trackpad. It requires me to lift my hand up and move to the track or mouse and then click. The entire process is counter-productive (at least for me). I find keyboard usage much more convenient and fast.

Recently I have been trying to select files in my finder window and I found out that I can't do it using keyboard only on Mac. Selection can only be triggered through a click.

Still, I wanted to know if anyone out there has found a solution to this? Can I select multiple (non-adjacent) files using keyboard only?
