I am going through the Blender 2.79b manual online here: https://docs.blender.org/manual/en/dev/interface/splash.html I don't see my question answered in it.
I have Blender open on my Mac. I have imported an svg file. I can select the File Browser view. I can see the folder URL to the Blender folder on my filesystem. There is a text box under this. There is a file directory under it.
I can type a filename in the box under the folder URL box and hit enter, but am not sure if it is having any effect -- it's not showing up in the file listing.
How do I save this or any blend as a .blend file? I can't shut down Blender until I figure this out!
