It would be great to be able to show/hide the Bookmarks Bar in Opera 21, similar to the CTRL+SHIFT+B toggle shortcut in the Chrome browser.
Yes, the Opera Bookmars Bar can be switched on and off in 'Settings', by selecting the 'Show Bookmarks Bar' option under 'User Interface'. This needs a press of Alt+P and then scrolling down the Settings/Browser menu to tick/un-tick the box.
A single-action toggle, such as the Chrome browser's Ctrl+Shift+B gives instant control over the bookmarks bar - allowing instant extra space for webpage display (and also speedily hides the bookmarks bar from prying eyes looking over your shoulder).
I have searched Opera extensions and Chrome store, without success.
If the Chrome browser can do it - then why not Opera 21?!
