I wanted a quick and easy way to enter sitecake edit mode on subpages of my site so I made a bookmarklet for one-click access:
It basically adds “/sitecake?scpage=“ to the URL’s domain and reloads the page.
I’m not sure if it’ll show up here but it is:
javascript:(function() { location.href ="/sitecake.php?scpage=" + window.location.pathname.substr(1); })();
You should be able to copy and paste that into

and follow the instructions to make your own bookmarklet.
