GetKeyView().viewInkWordScript := func(strokeBundle) begin

// convert the stroke bundle into an ink word

local inkPoly := CompressStrokes(strokeBundle);

local inkWord := inkPoly.ink;

local textSlot := "\uF701";

local stylesSlot := [1, inkWord];

local root := GetRoot();

// create a rich string with the ink word in it

local appendString := MakeRichString(textSlot,

stylesSlot);

// append the rich string to myRichString

if root.myRichString then

root.myRichString := root.myRichString && appendString;

root.myRichString := appendString;

// return nil so default handling still happens

This implementation converts the stroke bundle into an ink word, creates a rich

string that includes the ink word, and appends that rich string to a rich string that is

stored in the root (

myRichString). The method then returns nil, which allows

the built-in handling of the stroke bundle to occur.
