Power Ups are special sequences of text you can use to access powerful, advanced features. Click the Power Ups button above the turnsheet to open the menu. In the menu, click on a power-up to read its description, then copy and paste it into your turnsheet and click Update Preview to try it out.
Note: you can use power-ups in your Find & Replace Find column, Merge column headings, and in any Text type columns (they won't work in Rich Text columns).
