= Command Stack Dialog =

[[Image(source:/trunk/images/dialogs/commandstack.png,middle)]] ''Keyboard shortcut'': '''{{{Alt+Shift+O}}}''' — one of the [wikitr:/Help/ToggleDialogs#Toactivateawindow JOSM windows]

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

== Usage ==
This window 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 window. 

== Stack List ==
The stack displays one action per line with:
* [[Image(source:/trunk/images/data/key.png,middle)]] **Tags** representing changes on tags
* [[Image(source://trunk/images/data/sequence.svg,middle)]] **Sequence** representing geometrical changes on objects like adding, moving and deleting nodes or ways
* [[Image(source:/trunk/images/data/relation.png,middle)]] **Relation** representing changes of relations only
If multiple objects were changed in one action unfolding by clicking on the [[Image()]] 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 [[Image(source:/trunk/images/undo.svg,24,middle)]] Undo button or the [[Image(source:trunk/images/redo.svg,24,middle)]] Redo button is active but never both.

=== Select ===#Select
[[Image(source:/trunk/images/dialogs/select.png,middle)]] **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 ===
[[Image(source:/trunk/images/undo.svg,24,middle)]] **Undo** reverts all changes up to the currently selected action in the stack including the selected one.

=== Redo ===
[[Image(source:/trunk/images/redo.svg,24,middle)]] **Redo** reapplies all previously reverted changes down to the currently selected action in the stack including the selected one.
