If you open the dialog box by clicking on the group arrow
in the bottom right corner of the ribbon tab Review | group Changes, you can make various settings for the "Track Changes" function on the Review tab.
Note: You can also open this dialog box with the ribbon command File | Properties 
.
The following options are available:
"Comments" section
This section is responsible for inserting comments and not for the track changes feature. For more information, see Using comments.
"Comments pane" section
The comments pane is an area in the right margin of the page where the details of the changes can be clearly displayed.
For this purpose, the change actions Deleted text and Changed formatting in the "Changes" section (see below) must be set to In the comments pane. The change action Inserted Text is only displayed in the document text itself and never in the comments pane.
▪Width
| This option allows you to change the width of the comments pane. |
▪Position
| This option lets you change the position of the comments pane: in the right/left margin or outside/inside (for documents in book layout, i.e., with opposite pages). |
Note: You can set the width and position of the comments pane here in the same way as for the Comments function, because tracked changes and comments are displayed together in the comments pane. For more information, see also Using comments).
"Changes" section
▪Track changes
| This option enables/disables the tracking of changes. |
This button corresponds to the icon  on the ribbon tab Review | group Changes. |
▪Show changes
| This option enables/disables Show changes. If this option is enabled, changes are indicated. If it is disabled, the document appears as if all changes have been accepted. |
This button corresponds to the icon  on the ribbon tab Review | group Changes. |
▪Print changes
| If you enable this option, tracked changes will also be indicated in the printout instead of just on the screen. If it is disabled, the document will be printed as if all changes had been accepted. |
▪Show tooltips
| If this option is enabled, information about a change is automatically displayed on the screen when you hover over it (author, date and type of change). |
▪Inserted text, Deleted text, Changed formatting, etc.
| In the lower part of the dialog box, you can specify exactly how tracked changes should be indicated in the document: How would you like changes to be displayed in the document and in what color should such changes be highlighted? |
| Deleted text is displayed with a strikethrough in the document text by default, Changed formatting is displayed colored by default, and Inserted text is underlined by default. |
Tip: You can also display the change actions Deleted text and Changed formatting in a separate Comment pane to the right of the document, for example, if you set the default behavior for changes in this document accordingly (document-related).
| If you use the default setting Author for a color, a different color will be selected automatically for each user who edits the document. If the first user makes changes, they appear in red. If another user then opens the document and makes additional changes, they appear in blue, etc. |
Note: For this to work correctly, all users who edit the document must have specified their name in the TextMaker settings.
To enter your name, choose the ribbon command File | Options 
, switch to the General tab and enter your name using the User info button.
| The setting Edited lines causes a vertical line to appear in the page margin next to each change to further indicate that a change has been made at that point. |
