Beginner To Arduino, Questions

Hi, this is my first time attempting a project with arduino and I have a few questions before I start buying materials.

Can I live control the actions of an ardunio with my computer? For example if connect it to my laptop and I want the arduino to flash an led when I press the Caps Lock key, will it be able do that?

If yes, I noticed that there are many models of ardunio which one should I get for that purpose?
Or else, what could I get to do those actions?

Thank you so much!
