Final answer:
In Microsoft Word, to modify or delete an existing style, use the 'Manage Styles' option. For reviewing edits, use the 'Review' tab to accept or reject changes, where edits are indicated in red or as red text with a strikethrough.
Step-by-step explanation:
When working with Microsoft Word, making edits and styling documents are common tasks. If you need to modify or delete an existing style in a Word document, look for the Manage Styles option. To accept or reject changes made to a document, click on the Review tab located above the tools ribbon. This tab will also let you navigate through comments and track changes with functions like New Comment, Previous, Delete, Next, and Resolve.
Moreover, any edits that are made directly in the document will be easily identifiable. Added text will appear in red, while deleted text will show as red text with a strikethrough. This visual cue helps users to quickly see what changes have been made before finalizing the document.
