= Migrating From iD to JOSM =
== What is different ==
=== JOSM uses right mouse drag to pan a map ===
Unlike osm.org, most other editors and software, you have to hold right mouse click to navigate main a map in editing window.

=== Aerial imagery ===
* you have to enable Aerial imagery using [Help/Menu/Imagery Imagery menu] 
* additional sources can be installed via [Help/Preferences/Imagery Imagery tab in settings]

=== Searching in presets ===

Text search accessible via {{{F3}}} key, [Help/Action/TaggingPresetSearch Search presets].

=== JOSM is also an offline editor ===
In simplest case, it is possible to {{{Ctrl+O}}} [Help/Action/Open Open file] and {{{Ctrl+S}}} [Help/Action/Save Save file] with temporary edits. But there [wiki:Shortcuts#Workflow many more tools].

=== Shortcuts ===

Unfortunately, [wiki:Shortcuts JOSM shortcuts] are different from [http://wiki.openstreetmap.org/wiki/ID/Shortcuts iD]. Here is some details:

=== Relations ===

==== Tools to edit relations ====
* [Action/CreateMultipolygon Create a multi-polygon] {{{Ctrl+B}}}
* [Help/Dialog/RelationList Relation List] toggle dialogue
* [Help/Dialog/RelationEditor Relation Editor] - main interface when editing a relation
* [http://wiki.openstreetmap.org/wiki/JOSM/Plugins/Relation_Toolbox relation toolbox plugin] (optional)

==== Multipolygon relations ====

One day you will encounter [http://wiki.openstreetmap.org/wiki/Relation:multipolygon multipolygons]. Don't please don't be afraid of this big page, there [http://wiki.openstreetmap.org/wiki/Multipolygon_Examples slightly outdated guide (ignore tagging) with decent illustrations].
