Ctrl-W closes results table
I found by accident that Ctrl-W will close the table output (i.e. results of actionShowResultsAsTable) but will not close the list output. It's possible that this is intentional, but if so it would be nice if it were documented with the other keyboard shortcuts as I found it somewhat surprising. It's easy enough to get the results back by just pressing the table button twice, but I don't know what purpose hiding the results serves, so if this is not intentional this is a request to remove this keyboard shortcut.
This behavior occurs in both Recoll 1.28.0pre4 on Linux and Recoll 1.31.0 on Windows.
