ANTLR: Get token name?

Question

I've got a grammar rule,

OR
    : '|';

But when I print the AST using,

public static void Preorder(ITree tree, int depth)
{
    if (tree == null)
    {
        return;
    }

    for (int i = 0; i < depth; i++)
    {
        Console.Write("  ");
    }

    Console.WriteLine(tree);

    for(int i=0; i<tree.ChildCount; ++i)
        Preorder(tree.GetChild(i), depth + 1);
}

(Thanks Bart) it displays the actual | character. Is there a way I can get it to say "OR" instead?

robert inspired this answer.

if (ExpressionParser.tokenNames[tree.Type] == tree.Text)
    Console.WriteLine(tree.Text);
else
    Console.WriteLine("{0} '{1}'", ExpressionParser.tokenNames[tree.Type], tree.Text);
