Zoom

No keyboard shortcut (expert mode only) — is one of the working modes

With the Zoom mode the Map view can seamlessly be placed to specific area. Left click and drag a rectangle to zoom the viewport to that rectangle. If the zoom rectangle is drawn from top-left to bottom-right, you are zoomed in. If the zoom rectangle is drawn from bottom-right to top-left, you are zoomed out (since JOSM version 16900).

In all working modes zooming and scrolling the map is possible with:

• Using the mouse scroll wheel – Zoom
• + or Ctrl+, – Zoom in
• - or Ctrl+. – Zoom out
• drawing a rectangle in the Map view :
  • from top-left to bottom-right – Zoom in
  • from bottom-right to top-left – Zoom out
• Moving the slider top left in the Map view – Zoom
• Several entries in the View menu - Zoom and scroll
• Ctrl+Arrow – Scroll the map
• Right click and drag – Scroll the map
