+% See Figure~\ref{fig:distnodestable} for an illustration.
+%
+% \subsubsection*{Nodes}
+% Each timing line is a timing node (see section~\ref{sec:timingshape}) 
+% labeled (not fully correctly) as `|row|\meta{number}', where the first row has the number 1 and the last 
+% one the number provided in \cs{nrows}, but can also accessed using the alias "last row".
+% The corresponding labels are normal rectangle nodes named "label0", "label1", \dots,
+% `|label|\cs{nrows}'/"last label".
+%
+% Both groups of `rows' and `labels' are enclosed in a rectangle node called "all rows" and
+% "all labels", respectively. These nodes can be used to draw material relative to the rows,
+% \eg the macros \cs{tableheader} and \cs{tablerules} are making use of them.
+% The headers added by \cs{tableheader} are rectangle nodes names "label header" and "row header"
+% and are placed between the x-coordinates of the inner and outer border of "all labels" and "all rows"
+% respectively. By default the TikZ settings "pos=0" and "anchor=base east"/"anchor=base west", respectively,
+% are applied to place them in the inner border, but this
+% can be changed using the styles "timing/table/header" and/or "timing/table/label header"/"timing/table/row header".

+% used.
+% This keys are simply called \emph{TikZ Keys} throughout this manual and
+% can be used in all places where \meta{TikZ Keys} is mentioned, while some only make sense at specific
+% places.
+% Three types of keys 
+% are used by this package: styles, settings and actions.
+%
+% Styles simply define the style in which a certain element is drawn, \eg in which color or line width.
+% This styles are defined and can be redefined using 
+% \css{tikzset}|{|\meta{style name}|/.style=|\meta{value}|}|. However, while some styles
+% are initial empty, some hold internal settings and therefore user styles should only be added
+% using `|.append style=|\meta{value}'.
+%
+% Settings are TikZ keys which await an argument and set an internal macro or length. They are
+% like \cs{setlength} and \cs{renewcommand}. They should not be redefined by the user.
+%
+% Action are TikZ keys which perform a drawing or other action on the current element, either directly or
+% by en-/disable an internal setting which then in turn triggers the drawing process. Therefore some
+% actions can be globally and/or locally but others only make sense if used locally on a single |tikz-timing|
+% macro or environment or even a scope inside a \env{tikztimingtable}. 
+% Action can be very similar to settings but they always execute code instead of only setting/redefining it.
