The bar on the right (or left) next to the document is called a sidebar. It is a particularly useful tool:
For example, you can use the "Document map" 
function in the sidebar to display a list of all headings in a document in order to navigate better within the document. If you double-click on one of the headings, TextMaker immediately jumps to the corresponding heading in your document.
Using the sidebar
Use the small toolbar at the top of the sidebar to select which function should be used in the sidebar (document map, thumbnail preview, search, paragraph styles, character styles).
You can enable or disable the sidebar at any time:
To do so, choose the ribbon command View | group Windows | Sidebars 
(in the classic menu interface: View > Sidebars) and select the option Show sidebars. If you click on the enabled option again, you disable the sidebar.
If you choose the command Sidebars again while the sidebar is enabled, you can use the dropdown menu to freely arrange the individual functions in the sidebars to the left or right of the document. (If all functions are set to Show right, for example, only the right sidebar would then be displayed.)
Tip: When the sidebar is enabled, it can also be collapsed or expanded by clicking on the narrow vertical button at the edge of the sidebar. To adjust the width of the sidebar, drag the separator between the sidebar and the document to the left or right with the mouse.
Functions of the sidebar
You can use the small toolbar at the top of the sidebar to choose which function the sidebar should currently have. The following icons are available (from left to right):
Icon |
Function |
|
Show document map. For more information, see Navigating with the sidebar. |
|
Page thumbnails to display thumbnails of your current document. See example below. |
|
Search for search terms in the text. For more information, see Searching with the sidebar. |
|
Show, apply and edit paragraph styles. For more information, see Paragraph styles and the sidebar. |
|
Show, apply and edit character styles. For more information, see Character styles and the sidebar. |
By clicking on one of these icons, you can change the sidebar function at any time, depending on what you need.
The toolbar also has a menu that you can expand by clicking on the black arrow to the right of the toolbar. The menu contains two options that can be used to change the appearance of the toolbar as follows:
▪If you select the option Display as icons, all of the aforementioned functions will be displayed side by side as icons in the toolbar.
▪If, on the other hand, you select the option Display as list, only the currently selected function is displayed at the top instead, but all other functions can be accessed via the dropdown menu.
Example: The "Page thumbnails" function
The "Page thumbnails" function displays a page overview of the current document with small preview images (thumbnails) in the sidebar. This gives you a better overview of multi-page documents and enables you to easily navigate between the pages of a document.
To do so, click on the Page thumbnails icon 
at the top of the sidebar.
To jump to a specific page in the document, simply click on the respective preview image in the thumbnail.
