If the first few characters you type in a cell of the spreadsheet match an existing entry in that column, MedCalc fills in the remaining characters for you. MedCalc completes only those entries that contain text or a combination of text and numbers; entries that contain only numbers, dates, or times are not completed.
You can enable or disable the auto-complete function in the Options dialog box.
You can also select from a list of entries already in the column. To display the list, press ALT+DOWN ARROW to display the list, or right-click the cell, and then click Pick from List on the shortcut menu.
