For this example we will suppose that:
We want to enter the above formula (the value of pi rounded to 5 decimal places).
We know the name of the Greek character (â€œpiâ€).
But we do not know the markup associated with the symbol.
Step 1: Type â€œ%â€ followed by the text â€œpiâ€. This displays the Greek character .
Step 2: Open the Selection window (View > Selection).
Step 3: The symbol is a relation, so we click on the relations button . If you hover the mouse over this button you see the tooltip â€œRelationsâ€ (Figure 396).
Step 4: Delete the <?> text and add â€œ3.14159â€ at the end of the equation. Hence we end up with the markup â€œ %pi simeq 3.14159 â€. The result is shown in Figure 397.
