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 Imagery menu
• additional sources can be installed via Imagery tab in settings

Searching in presets

Text search accessible via F3 key, Search presets.

JOSM is also an offline editor

In simplest case, it is possible to Ctrl+O Open file and Ctrl+S Save file with temporary edits. But there many more tools.

B (background layer switcher)	differ	exact analogue	Help/Menu/Imagery menu, and be configured in Help/Preferences/Imagery
C, combines the selected objects	differ	similar tools	Merge Nodes M, Combine Ways C, Join Node to Way J, Ctrl+B [Action/CreateMultipolygon Create a multi-polygon]
D, unjoins the associated lines	differ	similar tools	G Unglue ways, there also tool for relations
Ctrl+C, copy the selected object	same	exact analogue	Ctrl+C copy the selected object
Ctrl+V, paste a previously copied object	same	exact analogue	Ctrl+V Paste from buffer
M, move objects	differ	exact analogue	Shift+←, Shift+↑, Shift+→, Shift+↓ or simply using mouse drag

R, rotate object	differ	exact analogue	Shift+Ctrl+ mouse move to [Help/Action/Select#Rotate rotate objects

pan one screen at time: Ctrl+←, Ctrl+↑, Ctrl+→, Ctrl+↓ or Shift+←, Shift+↑, Shift+→, Shift+↓

Relations

Tools to edit relations

• [Action/CreateMultipolygon Create a multi-polygon] Ctrl+B
• Relation List toggle dialogue
• Relation Editor - main interface when editing a relation
• ​relation toolbox plugin (optional)

Multipolygon relations

One day you will encounter ​multipolygons. Don't please don't be afraid of this big page, there ​slightly outdated guide (ignore tagging) with decent illustrations.
