## New Map Editor / View

### Adding a New Map Editor

This can be done in a few ways: using the **file menu**, **right clicking** on the tab bar, or using the **Ctrl+T** keyboard shortcut.

Using the file menu, simply go to: **File > New Map**.

This opens a new map editor tab with the default projection (CONUS Polar Stereographic).

To use the tab bar, **right-click** on or next to any tab and select **New Editor**

### Renaming Map Editor

Any of the map editor tabs can be renamed.  This can be particularly helpful if you have multiple tabs, with a different focus on each (ie. different geographic reigon, different types of data, etc).
