<A NAME="space"> <HR></A>
<H3>Key &lt;Space&gt;: regions vs. faces</H3>

 <P>Switches between the two basic modes region and face:

 <P><B>region</B> shows region cells;

 <P><B>face</B> shows boundary face cells;

<A NAME="o"> <HR></A>
<H3>Key o: Outer boundary faces on/off</H3>

 <P>If on, the boundary faces of the outer boundary will be shown.

 <P>Works in the face mode.

<A NAME="O"> <HR></A>
<H3>Key O: Switch Orientation</H3>

 <P>Changes the orientation of the faces.  This modifies the influence
of lights on the surface.

<A NAME="b"> <HR></A>
<H3>Key b: bad cells</H3>

 <P>Switches into a mode where only "bad" cells are shown.

<A NAME="R"> <HR></A>
<H3>Key R: Switch Region/Material</H3>

 <P>Switches the colors of cells/faces between two modes:

 <P><B>region</B>: color is defined by region: different colors for
different regions with the same material;

 <P><B>material</B>: color is defined by the material of the region:
same color for different regions with the same material;

<A NAME="p"> <HR></A>
<H3>Key p: Print mode</H3>

 <P>Defines which numbers should be printed

 <P><B>none</B> means nothing will be printed;

 <P><B>nodes</B> means node numbers of the printed cells will be printed;

 <P><B>cells</B> means cell numbers of the printed cells will be printed; 

 <P><B>all</B> means as node numbers, as cell numbers will be printed;

<A NAME="c"> <HR></A>

<H3>Key c: Choose a cell number</H3>

 <P>You have to type a number c and then press the &lt;Return&gt; key.
Then, only the cell with the number c (and its neighbours) will be
shown.

 <P>0 (no input before &lt;Return&gt;) returns to the default mode;

<A NAME="n"> <HR></A>

<H3>Key n: Choose a node number</H3>

 <P>You have to type a number n and then press the &lt;Return&gt; key.
Then, only the cells containing the node n will be shown.

 <P>0 (no input before &lt;Return&gt;) returns to the default mode;

<A NAME="r"> <HR></A>

<H3>Key r: Choose a region number</H3>

 <P>You have to type a number r and then press the &lt;Return&gt; key.
Then, only the cells of the given region will be shown.

 <P>negative value -r shows all regions except region r.

 <P>0 (no input before &lt;Return&gt;) returns to the default mode;

<A NAME="f"> <HR></A>
<H3>Key f: Choose a face number</H3>

 <P>You have to type a number f and then press the &lt;Return&gt; key.
Then, only the face cells of the given face will be shown.

 <P>negative value -f shows all faces except face f.

 <P>0 (no input before &lt;Return&gt;) returns to the default mode;

<A NAME="s"> <HR></A>
<H3>Key s: Shrink the cells</H3>

 <P>You have to type a number x and then press the &lt;Return&gt; key.
Then, the cells will be shrinked by x%.

 <P>0 (no input before &lt;Return&gt;) returns to the default mode (no
shrinking).

<A NAME="i"> <HR></A>
<H3>Key i: Info</H3>

 <P>Prints some info about the current grid.

<A NAME="return"> <HR></A>

<H3>Key &lt;Return&gt;: Center the picture</H3>

 <P>Centers the picture;
