How do I save a Blender file? 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!
As with most software, the keyboard shortcut to save a file is &#9096; Ctrl+S. A new window will open to navigate to wherever you want to save in your computer and specify the name the name of the file.

An alternative using the menu pressing file>save.
