Regions

An area is subdivided into regions.

Header (green), Main region (yellow), Tool bar (blue), Side bar (red) and Operator panel (pink).

Main Region

At least one region is always visible. It is called the Main region and is the most prominent part of the editor.

Each editor has a specific purpose, so the main region and the availability of additional regions are different between editors. See specific documentation about each editor in the Editors chapter.

Tool Bar

The Tool bar (on the left side of editor area) contains the tool settings. T toggles the visibility of Tool bar.

Operator Panel

The Operator panel is a region on 3D View that shows tool options when tools (operators) are run. Operator panel shows properties of the last operator executed.

Arranging

Scrolling

A region can be scrolled vertically and/or horizontally by dragging it with the MMB. If the region has no zoom level, it can be scrolled by using the Wheel, while the mouse hovers over it.

Changing the Size and Hiding

Resizing regions works by dragging their border, the same way as Areas.

Tip

Expand the Tool bar to show icons on two columns instead of one. Expand Tool bar more to show icons with titles.

To hide a region resize it down to nothing. A hidden region leaves a little plus sign (see picture below). By LMB on the plus sign, the region will reappear.
