It’s always fab to discover consistency of good ideas in MacOS and related applications.
For a long time, perhaps predating OSX, command-clicking on a Finder window’s title bar has given a menu enabling movement up the folder structure. (It’s a compact vertical equivalent to OSX’s excellent column view.)
I’ve just discovered a similar trick in Safari, Apple’s own browser.
This allows movement up the folder structure on the external web server. Hurrah!
Incidentally, the graphic in the Finder window is the unified theory of acceptance and use of technology. That’s a simple theory. If you want complex, look here – and scream.
