Using the inspectors

To display an inspector that is not currently on the screen, select its command from the Inspectors menu. To expand or collapse an inspector, click its title bar. To close an inspector, click the close button in its title bar. In the Inspectors menu there are some extra handy commands and keyboard shortcuts for managing inspectors.
Inspectors can be dragged around by their title bars like normal windows, but they will snap into place when you drag them near other inspectors, the document window, or the edge of the screen.
When you have inspectors attached to each other vertically, you can use the top inspector's title bar to drag all of them around together. The top inspector's close button will also close any attached inspectors. Dragging any inspector other than the top one will detach it from the inspectors above it.
Inspectors with a row of icons across the top (like the Appearance inspector) have several sections; click an icon to switch to that section. Click the icon again to close its section. You can command-click these icons or drag across several icons to open several sections at once.
