• Letter variables are listed in alphabetical order by replacement.
• The list can be re-sorted.

  You can re-sort the grid by clicking on an underlined column heading. It will sort in ascending order. Click it again to sort in descending order.
  
  A triangle next to the column heading indicates the column by which the grid is currently sorted and whether it is sorted in ascending or descending order.

1. To search for a specific variable, begin typing the replacement text in the Search field. The list is automatically filtered to display the variables that contain the characters you have typed.
2. When you locate the variable you want to retrieve, click the replacement. The lookup closes, and the letter is populated with the selected variable.

Click Cancel to close the lookup without selecting a variable.
