How do you apply a curve insert mesh?

I’m still new to zbrush and I’m using 4r7 and I’m trying to use the curve insert meshes but I don’t know how to apply the curve I made. I looked all around but all the curve mesh video tutorials I find don’t tell you how to apply the curve you just made, they just go on to making the next curve and I don’t know what they did. I unmask everything thinking that would do it because that’s all I see these tutorials do but when I try to apply another curve it just makes a new curve and gets rid of the one I just made! I was pushing some of the unmasking buttons and doing something I don’t know exactly what and was able to get one curve mesh to stay where it was when I made a new curve but I don’t know what I did. If someone could help me figure out how to apply the curve insert meshes I’d really appreciate it! thanks!

Click in the main geometry away of the curve.

thanks so much! I’m surprised that none of the tutorials on curves I watched ever mentioned it.
