Say we are on page 38 of some document, and we want to see the HTML source for the screen we are viewing. Well, typing \ gives us the source, however we are sent to page 1, the top. It would be neat if \ brought us right to (near) the spot we were browsing... however I bet it isn't all that simple...
It's not all that simple. For the case where source-caching is configured, and the file is in memory, it's "worked" since 2.8.6dev.12; however that won't work for some other cases (where the file is on local disk, and isn't cached).
