The following options are available:
▪ Comments and Comments pane sections

This button corresponds to the icon  on the ribbon tab Review | group Changes. |
▪Show changes

▪Print changes
| If this option is enabled, tracked changes are not only highlighted on the screen, but also in the printout. If it is disabled, the document is 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, etc.
| The options in the lower area of the dialog box let you specify how changes are to be represented in the document. Here, you can specify both the manner in which changes are to be displayed and the colors to be used to highlight the changes. |
| If you use the default setting Author for a color, a different color is 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 (or at least your initials) using the User info button.
