The RangeKerning property returns or specifies the amount of white space between the characters in a text object. This value represents a percentage of the Space character (that is, the character inserted when you press the Spacebar). The maximum value is 1000; the minimum value is -100.
Examples:
The following VBA example creates a text string and adjusts the kerning of the second word in it.
Sub Test()
Dim s As Shape
Set s = ActiveLayer.CreateArtisticText(4, 5, "Some loose text")
s.Text.FontPropertiesInRange(2, 1, cdrWordIndexing).RangeKerning = 100
End Sub
