Like I said, do you have a link because there is insufficient information in your code for us to judge?
Have you played with the padding on your menu wrapper, list items, (li) or menu links (li a), font-sizes etc?
As I said, with a live link we can inspect it and let you know.
In any case, I think I would be correct in saying that the VAST majority of users don’t Ctrl- very often, it’s more likely to be the opposite.
Oh…and it might be your search box too!
