Could you make Alt MouseLeft (Alt Enter) do the same thing (only within the Everything application)? I mean taking the path under the mouse cursor or highlited to the search field, and showing the content of the folder as result. That way a change directory is performed! While as before, a simple Mouse click (or just pressing Enter after selecting) or would open the Folder in Windows Explorer .
Then in a second step we want to go up in the tree. This could be done by Alt-Esc. Or make navigation arrows like in Windows Explorer (left of the bread crumbs path). This could truncate the path by one level, the remaining search string would be e.g. "D:\level1\" including the quotation marks.
Just ideas
