This command sums the total of all the numbers that appear in the selected area (columns or lines) and presents the total in a dialog box.
As some number formats have a comma, or other character that is part of the number or a separator (i.e. one thousand may be represented as 1,000) this may be configured. The dialog allows the user to specify any character that should be ignored in a number and by default is initialized to a comma (,).
The SUM button recalculates the total. It allows the separator to be modified and the total recalculated.
The TOTAL is shown in an editable entry box allowing the total to be formatted and copied to the clipboard and pasted into the document if required.
