 Internally, the sidebars are typeset by showing them as part of the headline. The \beamer\ class keeps track of six dimensions, three for each side: the variables |\beamer@leftsidebar| and |\beamer@rightsidebar| store the (horizontal) sizes of the side bars, the variables |\beamer@leftmargin| and |\beamer@rightmargin| store the distance between sidebar and text, and the macros |\Gm@lmargin| and |\Gm@rmargin| store the distance from the edge of the paper to the edge of the text. Thus the sum |\beamer@leftsidebar| and |\beamer@leftmargin| is exactly |\Gm@lmargin|. Thus, if you wish to put some text right next to the left sidebar, you might write |\hskip-\beamer@leftmargin| to get there.
 
+For convenience, the width of the sidebar and the height of its headline are accessible through the macros |\beamersidebarwidth| and |\beamerheadheight|, respectively.

+  Allows the user to set their own aspect ratio. For the height of the resulting frame, the default value of 96\,mm is used and the width will be calculated accordingly to match the desired aspect ratio.

 This command will create a frame containing four slides. The first will contain the text ``This is slide number~1,'' the second ``This is slide number~2,'' the third ``This is slide number~4,'' and the fourth ``This is slide number~5.''
 
 A useful specification is just |<0>|, which causes the frame to have no slides at all. For example, |\begin{frame}<handout:0>| causes the frame to be suppressed in the handout version, but to be shown normally in all other versions. Another useful specification is |<beamer>|, which causes the frame to be shown normally in |beamer| mode, but to be suppressed in all other versions.
+
+Frames which are hidden with |<0>| behave like the |noframenumbering| option and will not be counted for the number of frames (this only applies if no mode is specified, e.g. not for |<all:0>|).

In some situations, you can use the |\only| command for this purpose. However, the command |\mode|, which is described in the following, is much more powerful than |\only|.
