importing public keys from websites

I need to import a public key from a website.I have been told to copy the text save it as a text file and then import it to either kleopatra or GPA however when I try to do this the message imported keys 0.or could not determine type of key occurs.I am using 64 bit windows 8.I do not know the name of said person so cannot look up the key on keyserver this is driving me nuts as I have seen a video of it being done and the process looked simple

What is the name (including extension) of the public key file?
