Range -1 to 10
<$range tiddler="$:/_RangeDemo/1" min="-1" max="10" default="1" increment="1"/> {{$:/_RangeDemo/1}}
That renders as:
Range 0 to 1
<$range tiddler="$:/_RangeDemo/2" min="0" max="1" default=".01" increment=".01"/> {{$:/_RangeDemo/2}}
That renders as:

<$action-setfield $tiddler="""$tiddler$""" $index=<<now "0hh-0mm-0ss:0XXX">> $value=<<getText>>/>
</$vars>
\end
\define clear-range-log(tiddler:"$:/temp/range/log")
<$action-setfield $tiddler="""$tiddler$""" text="{}" show=show/>
