To exit Edit Mode in Blender and return to Object Mode, simply press the Tab key. This is the standard and most efficient method.
Understanding Blender's Modes and Undo Functionality
Blender operates using different modes, such as Object Mode, Edit Mode, Sculpt Mode, and others. Each mode offers specific tools and functionalities. Edit Mode allows for detailed manipulation of a mesh's vertices, edges, and faces. Exiting Edit Mode, therefore, means returning to a broader level of object manipulation.
The Tab key acts as a toggle between Object Mode and Edit Mode. Pressing it once will exit Edit Mode; pressing it again will re-enter it.
Undoing Actions Within Edit Mode
If you want to undo actions within Edit Mode, use the standard undo shortcut: Ctrl+Z (or Cmd+Z on macOS). This will revert your most recent action. You can repeat this shortcut to undo multiple steps. Blender maintains a history of your actions, accessible via the Edit > Undo History menu or the shortcut Ctrl+Alt+Z (or Cmd+Option+Z on macOS).
Blender's undo functionality is generally "global", meaning actions made in Edit Mode are included in the global undo history (as confirmed by several sources, such as the Blender Stack Exchange and the Blender 2.8 Undo System Discussion). However, some add-ons or specific actions might behave differently, as noted in discussions regarding Python API operators and undo support in the Blender Developer Forum.
Troubleshooting
-
If Ctrl+Z isn't working: Ensure "Global Undo" is enabled in Edit > Preferences > Editing. This setting is discussed in relation to potential undo issues on Blender Stack Exchange.
-
Add-on Conflicts: Certain add-ons might interfere with standard undo functionality. Temporarily disabling suspect add-ons may resolve the problem.
-
Specific Scenarios: In specialized scenarios like the node editor, the undo functionality might vary depending on the specific context, as indicated in a discussion on Blender Artists.
