"Control" condition (MouseKeyboard)

In the Platform School cap (lesson 2): as a new condition for MouseKeyboard, you can choose "Control is down?" and "On Control pressed".

When you select this condition, it starts with empty quotes: "".

The tutorial enters here "Move Right".

Question: what other options can be used here? Move Up? too?

I can, and will, try out some directions, but where can I find the list/options to choose from?

If it only starts with empty quotes, I don't know what the condition accepts or not.

you can type whatever you want. in the application properties, you set which key correlates with which controls (where you can also input your own).

Thanks, I never noticed Controls in Application Properties before.

It does mention in that same lesson that you can change the controls in the application properties
