How to GetMousePosition?

I want to create a scheme that will trigger an event or function by mouse movement, drawing a symbols by mouse.
Press the input button>create a sign>activate trigger
Similar systems were in Arx Fatalis or HP 1(the game).
I was told to use Get Mouse Position but i really don’t understand how to. Help!

Did you try typing: “Get Mouse Position”?

Well, I must say that I did not find the same node as you have! But I tried to work with what was. Take a look. It was an attempt to bring the cursor to the center of the screen.
Then I realized that I needed help.

I think this is it.
