    56This is the main view in JOSM (also called [https://en.wikipedia.org/wiki/Viewport Viewport]), where editing takes place, and Bing/Mapbox and other sources can be displayed.

     10== What do you see here and when ==
    1111There are several mechanisms in JOSM that affect what the user sees in the map view.

    13 ==== Visibility ====
    14 
     13=== Visibility ===
    1514* Data can be ''filtered out'' by [wikitr:/Help/Dialog/Filter Filters]
    1615* [wikitr:/Help/Dialog/LayerList Layers (data, imagery)]
    … …  
    1918* Map Paint Styles can hide OSM objects per zoom level
    2019
    21 ==== Appearance ====
    22 
    23 * '''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.
    24 * Enabled (in [wikitr:/Help/Preferences/Map#MapPaintStyles preferences]) and activated (in [wikitr:/Help/Dialog/MapPaint Map Paint Styles window] or preferences) styles affect what you see on the screen

     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:

     34=== Zoom ===
    3735* Using the scroll wheel
    38 * {{{+}}} and {{{-}}} keys
     36* `+` and `-` keys
    3937* more specialized move/zoom actions and tools like:
    40  * several entries in the [wikitr:/Help/Menu/View View menu]
     38 * several items in the [wikitr:/Help/Menu/View View menu]
    4139 * [wikitr:/Help/Action/JumpToPosition Jump To Position]
    4240 * [wikitr:/Help/Action/Zoom Zoom tool]
    4341 * [wikitr:/Help/Dialog/Minimap Minimap]

    49 JOSM will limit your editing abilities outside of the area that you have downloaded, because it may lead to [wikitr:/Help/Concepts/Conflict conflict] after upload.
     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.

    51 Another precaution is not to draw new objects in undownloaded area because it may lead to duplicates (because of not-downloaded-yet and not visible objects in your viewport).
     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.
     52
     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.

    55 On a Mac with a one-button mouse, simulate right-click by holding down {{{Ctrl}}} while clicking the button.
