@@ -19,6 +19,7 @@ Several bang-commands are available to control output formatting:
 * `!col_threshold <N>` to set the threshold at which entries get columns rather than being left as notes on the right.  Default: 2
 * `!hide <column>` to omit a column
 * `!label <column>:<new label>` to change a column's label without needing to change all the input occurrences.
+* `!mark <column>:<mark>` to change the character that is used as the tally-mark for that column
