Inserting more than one row/column at a time
- To insert multiple rows into a Calc spreadsheet at one time, select the same number of rows as you want to add, beginning at the row AFTER where you want the insertion to be, then
- Ctrl-click/right-click on the row header (where the row numbers are) within your selection, and choose Insert Rows from the contextual menu, or
- Click on the "Insert Rows" button in your toolbar (if it's visible there), or
- Choose Rows from the Insert menu.
- To insert multiple columns, just follow the above instructions subtituting 'columns' for 'rows' - it works exactly the same way.
