Hold down the 1 key and click.

It does not work for me. Please help me.

What are you trying to accomplish? you want to implement this on your game or is this some editor shorcut that doesn’t work. I don’t know if I am dumb or your question is hard to understand.

That is the video. My question begins at min, 5:00.

Ok you can do it in an alternative way, instead of 1 and click, do right click, search constant(only constant no 2-constant or 3-constant), then do the same right click and convert to parameter

Thank you thank you thank you It worked. I have been searching for the answer this entire day haha
