Adjusting type size??

[kirab]

Could you please help me?? I was writing an e-mail on my roundcube when by mistake I pressed the Ctrl key while holding down the underline key and suddenly the type size started getting smaller and smaller till it almost disappeared. I've tried all sorts of things to get it back to normal type size, but I just can't!!! Now I can't even read anything or even register on this forum with that e-mail address 'cause I can't see a thing!!! Could someone please help me and tell me how to adjust type size in my e-mailbox? Thanks so much!

Try hitting "Ctrl 0" or "Ctrl +" you should also be able to change the size in your browsers view menu.
