size of url box?

edit

The OQ assumably referred to the 'Load URL' box (name misleading) containing the absolute filepath of the current document if already existing). If enabled It is the first element in the standard toolbar and cannot be redimensioned (afaik).

@Lupp Thank You . Never knew it was there. Should have with all the clarity in question. :)

I need clarification. If I understand, the arrow to the right. I found it, thank you. What I should have asked 'can I change the font size inside that box as it is very hard to see?

Sorry, I personally don't know where or if that can be changed.
