= Map View =

This is the main view in JOSM (called [https://en.wikipedia.org/wiki/Viewport Viewport] by experts), where editing takes place, and Bing/Mapbox and other sources can be displayed.

=== What do you see here and when ===

There several mechanisms in JOSM that affect what user sees in main screen.

==== Visibility ====

* Data can be ''filtered out'' by [[Help/Dialog/Filter|Filters]]
* [[Help/Dialog/LayerList|Layers (data, imagery)]] can be [[Help/Dialog/LayerList#LayerButtons|hidden]] or [[Help/Dialog/LayerList#VisibilityLayer|semi-opaque]]
* Map Paint Styles can hide objects per zoom level

==== Appearance ====

* Partial fill of objects is enabled by default, it depends on area of the object. 
* Enabled (in [[Help/Preferences/Map#MapPaintStyles|preferences]]) and activated (in [[Help/Dialog/MapPaint|Map Paint Styles window]] or preferences) styles affect what you see on the screen
* Styles can be displayed differently based on zoom factor

=== Move map ===
The area displayed in the window can be moved by holding down the right mouse button, and dragging the mouse. (On a Mac with a one-button mouse, simulate right-click by holding down **`Ctrl`** while clicking the button.)

=== Zoom ===
You can zoom using the scroll wheel or the `Plus`- and `Minus`-keys but there [wiki:Help#Viewportcontrol many alternative ways].
