Word has a status bar at the bottom which gives you useful information about your document.
You can customise the things you want to see in the status bar to suit your needs. For example
- Showing the sections can be useful if you are using section breaks in your documents
- Showing the word count is useful to track your writing productivity or if you are working to word limits
- Showing whether tracked changes are on is useful if you are often using tracked changes
Even better, the things showing in the status bar have functionality if you click on them. For example clicking on tracked changes toggles this on and off.
You can set the options for what you want to see by right clicking in the status bar and selecting the tools you want to show.
