The number of styles in the selection list increases without you having done a thing. The additional entries come with the suffix "char". What's going on here?
This happens when. you assign the "Paragraph" style to a selected character or word. Word then automatically creates a new combined style and makes a distinction between the two by placing "Char" after the name of the new style. This not only makes the list more confusing, but could also result in inconsistent formatting. Unfortunately, there is no one-click option to prevent such weird behavior.
To prevent this from happening, format individual words by defining special styles for them rather than formatting individual selections. This is how you can go about it: open" Format I Styles and Formatting" and click" New Style". Now set "Character" in the "Style type" combination field. Then define the actual formatting, give it a name and finally create the style by clicking "OK". There will be a small symbol for the character style to the right of the name of the format template in the selection box. There is no symbol for automatically created or combined templates.
To check if and where a particular format template has been used in the text, go to "Edit I Find", click "More" and open "Format I Style" in the following dialog. Select the entry in question and confirm it with "OK". Now keep clicking "Find next" to navigate to the respective selections in the document. You can even correct paragraph formatting while doing so.
To remove unused templates, open "Tools I Templates and Add-Ins". Click "Organizer" in the dialog that opens and activate the "Styles" tab. On the left, select the respective style in the list of the active document and click on the "Delete" button. Confirm the confirmation prompt with "Yes".
