+====== TOTAL/SUBTOTALS ======
+Category: Transform / Math\\
+\\
+=====Description=====
+This action appends to a dataset a new column that contains an aggregated total for selected column, or subtotals for groups.\\
+\\
+=====Use cases=====
+Create a "total" column to calculate a total or group percentage value with (e.g. total value/ group value).\\
+\\
+=====Action settings=====
+^Setting^Description^
+|New column|Enter a name for the new total/subtotal column.|
+|Target column|Select the numeric column used to generate the aggregate values.|
+|Mode|Select the aggregation mode.  Options:  //Sum//, //Count//, //Average//, //Min//, and //Max//.|
+|Groups|Select whether to derive the total/subtotal value across all rows in the dataset, or grouped by selected columns.\\  Options:  //Column total// or //Subtotal inside groups// (and select the columns to subtotal by).|
+\\
+=====Remarks=====
+The new column will appear as the rightmost column in the dataset, by default.
+The grouping aspect of the //Subtotal inside groups// option is case sensitive.  Values in the grouping column(s) having different cases will be calculated as unique values (e.g. not combined).\\
+\\
