Function eject key not working on wireless keyboard?

I noticed that the eject button does not work on my wireless keyboard when holding the function key?
I have an external cd drive and in Ginder I notice that the shortcut is 'cmd E'.

How do get the Fn key working as it should please?
Can I change the shortcut in Finder?


Thanks

 

Thanks for the help.

I have a 2012 iMac without the internal hard drive which the key was probably designed for. I think I will just drag the icon to the waste to eject the cd or press 'cmd E'.

I just thought that there was something wrong with the key.
