Selection window

keyboard shortcut: Shift+Alt+T — one of the JOSM windows

This list shows the currently selected objects (nodes, ways, closed ways and relations).

Selection

• Selection is independent per each layer
  • Selection in other layers will be preserved after an unsuccessful search - it is safe to change (or even erase) selection in one layer and expect to selection in other layer to kept
  • Selection in the active layer will be empty after unsuccessful search
• There at least 2 tools to recover history of last selected objects:
  • Small triangle in "Select" button from this page
  • Special syntax in the search action - selection based on list of objects save in the file
• Selection is ordered (internally, but you cannot control order except by re-selecting objects); practical use of it can be seen in MergeNodes
• This window has not 3, but 5 control elements in total. Triangles are often overlooked at first, but provide a very powerful tools
• List of currently selected object(s) can be erased:
  • after Left mouse click on empty space in viewport (main editing window)
  • after using one of many Deselection tools
  • after running search query (explained above)
  • after Escape tool
• Items in Selection window can be subselected

Subselection

Items in selection can be "selected" again (subselected)

• Mouse click to subselect single object
• Hold Ctrl
  • to subselect more than object
  • to remove subselection from objects

Single node Spielemax subselected in screen below

Context menu

• "Zoom to selection" - zoom to all items in selection
• "Zoom to selected elements" - zoom to subselection

Items below apply only to relations

• "Select in relation list" - open Relation list
• "Edit" - open Relation editor
• "Download incomplete members"

Naming

• Nodes are shown with their names (likewise their OSM-ID) and their position in brackets.
• Ways and closed ways are shown with their names and if no name-tags exist with their main tag (eg highway, landuse, railway ...). If JOSM is not able to interpreted any tag the OSM-IDs are shown. The numbers of nodes the ways consist of are always shown in brackets.
• Relations are shown with their type and in brackets the name and the number of members.
