= Command Stack Dialog =

[[JOSMImage(dialogs/commandstack,link=,48,middle,margin-right=20)]] ''Keyboard shortcut'': **`Alt+Shift+O`** — one of the [wikitr:/Help/ToggleDialogs#Toactivateawindow JOSM panels]

This sidebar panel shows all commands issued. [[Image(command_list_dialog.png,link=,right,margin-left=10,margin-bottom=10)]]


== Usage ==
This panel can be used to spot mistakes during editing in JOSM and to undo/redo several actions at once.

**Note**: Josm uses only one stack for all OSM-Data layers and there is no indication of layer switches in the panel. 


== Stack List ==
The stack displays one action per line with:
* [[JOSMImage(dialogs/propertiesdialog,link=,16,middle)]] **Tags** representing changes on [wikitr:/Help/Concepts/Object#Tags1 tags]
* [[JOSMImage(data/sequence)]] **Sequence** representing geometrical changes on objects like adding, moving and deleting [[JOSMImage(data/node)]] [wikitr:/Help/Concepts/Object#Nodes nodes] or [[JOSMImage(data/way)]] [wikitr:/Help/Concepts/Object#Ways ways]
* [[JOSMImage(data/relation)]] **Relation** representing changes of [[JOSMImage(data/relation)]] [wikitr:/Help/Concepts/Object#Relations relations] only
If multiple objects were changed in one action unfolding by clicking on the [[JOSMImage(svpRight,link=,8,middle)]] anchor on the left will show one object per line. Depending on the action folding might not be supported or even another unfold is needed to show the objects.

A thin horizontal line displays the current position with in the stack which is rendered in [wikitr:/Help/MapView Map View].


== Control buttons ==
**Note:** Depending on the selection in the stack either the [[JOSMImage(undo,link=,24,middle)]] Undo button or the [[JOSMImage(redo,link=,24,middle)]] Redo button is active but never both.

=== Select ===#Select
[[JOSMImage(dialogs/select)]] **Select** selects all objects  which are not deleted and were modified by the currently selected action in the stack. If an object is selected in the stack it is selected. 

=== Undo ===
[[JOSMImage(undo,link=,24,middle)]] **Undo** reverts all changes up to the currently selected action in the stack including the selected one.

=== Redo ===
[[JOSMImage(redo,link=,24,middle)]] **Redo** reapplies all previously reverted changes down to the currently selected action in the stack including the selected one.
