Editing Blender (software) (section)

==User interface==
[[File:Blender Version 2.570.jpg|300px|thumb|Blender's user interface underwent a significant update with Blender 2.57, and again with the release of Blender 2.80.]]

===Commands===
Most of the commands are accessible via [[Keyboard shortcut|hotkeys]]. There are also comprehensive graphical menus. Numeric buttons can be "dragged" to change their value directly without the need to aim at a particular widget, as well as being set using the keyboard. Both sliders and number buttons can be constrained to various step sizes with modifiers like the {{mono|Ctrl}} and {{mono|Shift}} keys. [[Python (programming language)|Python]] expressions can also be typed directly into number entry fields, allowing mathematical expressions to specify values.

===Modes===
Blender includes many modes for interacting with objects, the two primary ones being ''Object Mode'' and ''Edit Mode'', which are toggled with the {{mono|Tab}} key. Object mode is used to manipulate individual objects as a unit, while Edit mode is used to manipulate the actual object data. For example, an Object Mode can be used to move, scale, and rotate entire [[polygon mesh]]es, and Edit Mode can be used to manipulate the individual vertices of a single mesh. There are also several other modes, such as Vertex Paint, Weight Paint, and Sculpt Mode.

===Workspaces===
The Blender GUI builds its tiled windowing system on top of one or multiple windows provided by the underlying platform. One platform window (often sized to fill the screen) is divided into sections and subsections that can be of any type of Blender's views or window types. The user can define multiple layouts of such Blender windows, called screens, and switch quickly between them by selecting from a menu or with keyboard shortcuts. Each window type's own GUI elements can be controlled with the same tools that manipulate the 3D view. For example, one can zoom in and out of GUI-buttons using similar controls, one zooms in and out in the 3D viewport. The GUI viewport and screen layout are fully user-customizable. It is possible to set up the interface for specific tasks such as video editing or UV mapping or texturing by hiding features not used for the task.
