Answer 1

ssh-keygen supports -f to specify the filename, so you can use it

 -f filename
        Specifies the filename of the key file.

Answer 2

-f filename is used to directly indicate the name of the key to be created. But it shows with the tab all the existing keys with the same first letter indicated.

But i have again the incapacity to find the newest key in .ssh. .ssh not creating
