An area is subdivided into regions.
At least one region is always visible. It is called the Main region and is the most prominent part of the editor.
每个编辑器都有特定的用途，所以每个编辑器的主区块和附加区域的功能都是不一样的。更多信息见 编辑器 章节中各编辑器对应文档。
标题栏是位于区域顶部或底部以浅灰色为背景的水平长条。所有编辑器的标题栏都作为菜单和常用工具的容器。 菜单 和按钮随编辑器类型以及选中对象及其模式而变化。
All hotkeys you press will affect the contents of the editor where mouse pointer is located.
The Tool bar (on the left side of editor area) contains the tool settings. T toggles the visibility of Tool bar.
The Side bar (on the right side of editor area) contains Panels with settings of objects within the editor and the editor itself. N toggles the visibility of Side bar.
区块可以拖动 MMB 垂直/水平滚动，如果该区块没有缩放级别，鼠标停留在上方即可使用 Wheel 滚动。
Resizing regions works by dragging their border, the same way as 区域.
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.
