Resize boxes on bottom line (secure display)

[kwunder]

At the bottom of a web page, where you get the line of info about what page is loading / where a link is poitning, further to the right you get 3 little boxes, one of which displays the padlock icon on a secure site. My questions are as follows :-

1) I know one of the other three displays an eye which is something to do with cookies, but, what is the third one for ?

2) Can they have their sizes altererd with a registry tweak of some other method, as on some secure sites, I can see the padlock and also the start of some text to the right, which is mostly hidden.

Thanks
