The status bar displays the cursor location, drawing tools, and tools that affect your drawing environment.
The status bar provides quick access to some of the most commonly used drawing tools. You can toggle settings such as grid, snap, polar tracking, and object snap. You can also access additional settings for some of these tools by clicking their drop down arrows.
Note: Not all tools are displayed by default; you can choose what tools to display from the Customization menu, the right-most button on the status bar. The tools displayed on the status bar might change depending on the current workspace and whether the Model tab or a layout tab is currently displayed.
You can also toggle some of these settings with the function keys on your keyboard (F1 - F12).
