If your worksheet has left and right pages you may want your headers and footers to reflect this, so that text and page numbers appear in the outer corners of the bound pages.
To set up alternating headers:
Create the header and/or footer on the first page; this will usually be a right-hand page.
Choose Pages from the Page menu.
Select the Page 1 entry and click Change in the Pages dialogue box which appears.
Click on the switch for Even header or Even footer, as required. You can alter the margin and offset settings; they will first appear identical to the original header and footer.
Go to an even numbered page and type in the text for the new header or footer.
Create a new header or footer style based on the BaseHeadFoot style, adding the tabs and other style features you want to use. Call it something like Left Header.
The two headers will automatically appear on opposing pages throughout the document.
