To insert headers, click on the Header icon 
on the ribbon tab Insert | group Header and footer. Alternatively, click on the icon's arrow to apply an appropriate header format when inserting directly from the dropdown menu with predefined formats.
TextMaker then positions the text cursor in the header frame in the top margin of the page. Here, you can enter and format text as usual.
The header frame is initially only one line in size, but it expands automatically when you type more than one line of text or start a new line by pressing the Enter key↵.
To return to the normal text from the header frame, just click anywhere in the normal text with the mouse. If you want to edit the headers again later, click in the header frame with the mouse. You can also just click again on the Header icon or use the icon's arrow to select Edit headers in the dropdown menu.
The insertion and editing of footers is performed in a similar way. You use the Footer icon 
on the ribbon tab Insert to create footers in the bottom margin of the page. If you click on the icon's arrow, you will find a selection of predefined formats and the command Edit footers.
Note: Headers and footers apply to the whole document by default. If you want to use different headers and footers within the same document, you must divide the document into chapters. You can then enter different headers and footers for each chapter. For more information, see Dividing a document into chapters.
