## Navigating the map

***To move around*** the map, click and drag.

***To zoom in and out*****,** you can use the <img src="/files/P5DskqENv0yem6mjrUXM" alt="" data-size="line"> and <img src="/files/w5whsAYovPoLOdojLPi4" alt="" data-size="line"> buttons in the top right corner of the map, or the scroll wheel on your mouse (or equivalent hand gesture on a touchpad). Using the scroll wheel or touchpad offers more granular zooming.

***To rotate the map or adjust the viewing angle***, right click and drag. To return to a northward orientation, you can click the <img src="/files/U4iWfSqdJSYfwLkqPayf" alt="" data-size="line"> button in the top right

***To zoom in on a particular area***, hold `shift` and click and drag your cursor. A rectangle should appear — this rectangle will become the new bounds of the map viewer window.
