There isn't a key or command to simply "refresh" a view
(normaly in win appl. key F5). For example if I select a
folder to view only unread item, after I have read them the
only way to refresh the window is to click to another feed
and then reclick the folder.
In "customize toolbar" there is an action named "refresh
feedlist" but it haven't an icon nor a Fkey and if I drop it to
the toolbar it not work.
