[Orgmode] todos without timestamp in agenda

[henry atting]

When I have some kind of todo items in an *.org file without timestamp they
do not show up in the agenda. I can start the agenda with the
appropriate shortcut then only these items are diplayed. 
But if I am already in org-agenda I have to quit then start again
with the speacial agenda view.
Is there a more comfortable way to simply switch the view when in
org-agenda, or let these todo items show up in the first place (e.g. at
the bottom of the agenda)?

Cheers
henry
