Thanks for your quick reply aeyoun,
I assumed that I could use the same combo as for Firefox fullscreen mode (which is command-shift-f).
Now I know better!

Hello folks,
I recently updated to Opera 24 and when I use my usual key sequence to change into fullscreen mode,
the address bar gets cut off. The only solution i found out so far is to leave fullscreen and and get right back in it
quoties opus sit until the address bar is visible again.
Any ideas?
