select

{select:value,listname}
{select:value,listname,object}

Returns the value of a single list item from a sparse property list.

The item chosen is the one who's line number is the largest one that is less than or equal to the given value. If the list is missing any items, then {select} will return the item in the list with the highest line number that is less than or equal to the given value.

ie: If the list has the following entries:

    _junk#/1:one
    _junk#/5:two
    _junk#/16:three
    _junk#/20:four

Then

{select:9,_junk}

will return "two",

{select:16,_junk}

will return "three", and

{select:25,_junk}

will return "four".
