Possible to set focus to link with onmouseover?

Hi everyone. I'm a noob and I think this is my first post here.
Does anyone know if it is possible to set focus to a control with a mouse over and display the link no. in a message box?

Thanks in advance for any responses

 

If you're you trying to do some kind of tooltip, you can take a look at overlib

 

onmouseover="alert(linknr);this.focus();" ?

 

Thank you both very much. This helps much.
