I revised to "Close the box with ...", parallel to previous sentence. As to structure, we have a 3 dimensions: Open method (wait, hot key, tab), namespace (main, attribute, files), and stage (open select, close), with some cells blank (wait never opens the main namespace) and some entries identical. The existing order made little sense to me. I started with select and close because these are common to all open methods and lists. I made this more explicit. I follow with the 3 invocation methods and module level completions.

In any case, there are more edits all through the doc and a will wait a day for more comments before merging.
