    6 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.
     6This is the main view in JOSM (also called [ Viewport]), where editing takes place, and Bing/Mapbox and other sources can be displayed.
     10== What do you see here and when ==
     11There are several mechanisms in JOSM that affect what the user sees in the map view.
     13=== Visibility ===
     14* Data can be ''filtered out'' by [wikitr:/Help/Dialog/Filter Filters]
     15* [wikitr:/Help/Dialog/LayerList Layers (data, imagery)]
     16 * can be [wikitr:/Help/Dialog/LayerList#LayerButtons hidden] or can be set to [wikitr:/Help/Dialog/LayerList#VisibilityLayer semi-opaque]
     17 * can be obscured by other data layers ([wikitr:/Help/Dialog/LayerList#PanelButtons Up/Down buttons] are used to arrange layers)
     18* Map Paint Styles can hide OSM objects per zoom level
     20=== Appearance ===
     21* '''Partial fill of objects''' is enabled by default, it '''depends on area of the object'''. Areas will be fully filled if ''the partial fill would cover more than 50% of the area'' to avoid small unfilled gaps in the middle of an area.
     22* Enabled (in [wikitr:/Help/Preferences/MapPaintPreference preferences]) and activated (in [wikitr:/Help/Dialog/MapPaint Map Paint Styles panel] or preferences) styles affect what you see on the screen
     23* Styles can be displayed differently based on zoom factor
     26== Map view controls ==
     27=== Move map ===
     28The area can be moved by '''holding down''' the {{{right mouse button}}}, and '''dragging''' the mouse. To improve dragging performance, labels are hidden while moving the map:
     32This can be disabled in the [wikitr:/Help/Preferences/DrawingPreference OSM Data settings].
     34=== Zoom ===
     35* Using the scroll wheel
     36* {{{+}}} and {{{-}}} keys
     37* more specialized move/zoom actions and tools like:
     38 * several items in the [wikitr:/Help/Menu/View View menu]
     39 * [wikitr:/Help/Action/JumpToPosition Jump To Position]
     40 * [wikitr:/Help/Action/Zoom Zoom tool]
     41 * [wikitr:/Help/Dialog/Minimap Minimap]
     44== Downloaded area ==#Downloadedarea
     46#Downloadedarea target is called from Help/ExpertMode page
     49The area which was ''not'' downloaded is indicated by a yellow hatching. Ways which were downloaded can reach into the hatched area though. Make sure to edit only in the non hatched area because else it may lead to [wikitr:/Help/Concepts/Conflict conflicts] or duplicate data after upload.
     51Note that if you download filtered data (e.g. only buildings via [wikitr:/Help/Action/Download Overpass API]) there will be no hatched area at all as this is an incomplete data set. As soon as you download an additional area (containing all data in this area) into this layer the hatching will appear.
     53In special editing scenarios it may be useful to disable the hatching. This can be done via the [wikitr:/Help/Menu/View View menu] ([wikitr:/Help/ExpertMode expert mode] only) or in the [wikitr:/Help/Preferences/DrawingPreference OSM Data settings]. Use this with caution. Only disable the hatching if you know what you are doing.
     56== Troubleshooting ==
     57On a Mac with a one-button mouse, simulate right-click by holding down {{{Ctrl}}} while clicking the button.
     60== See also ==
     61* '''[wikitr:/Help/Action/Select Select Action]''' - help on selecting, moving, and rotating objects in the map view
     62* '''[wikitr:/Help/EditToolbar Modes]''' - overview of modes (frequently accessed tools) in JOSM
     63* [wikitr:/Help/StatusBar Status bar]
     64* [wikitr:/Help/Menu/ImageryContextMenu Imagery Context Menu]
