Change Interface preferences

Choose Edit > Preferences > Interface (Windows) or InDesign > Preferences > Interface (Mac OS).
Choose the settings you want to specify, and click OK.

Tool Tips: Tool tips appear when you hold the mouse pointer over interface items such as tools in the toolbar and options in the Control panel. Deselect this option to turn off tool tips.
Show Thumbnails On Place: When you place a graphic, a thumbnail of the image appears in the loaded graphics cursor. Similarly, a thumbnail of the first few lines of text appears in the loaded text cursor. Deselect this option if you don’t want thumbnails to appear when placing graphics or text.
Show Transformation Values: When you’re creating, sizing, or rotating an object, the cursor displays the [x,y] coordinates, width and height, or rotation information.
Floating Tools Panel: Specify whether the toolbar appears as a single column, double column, or single row.
Auto-Collapse Icon Panels: When this option is selected, clicking the document window closes the open panel automatically.
Auto-Show Hidden Panels: When you hide panels by pressing Tab, holding the mouse pointer over the side of the document window temporarily reveals the panels if this option is selected. If this option is not selected, you must press Tab again to display panels.
Open Documents As Tabs: When this option is selected, documents you create or open appear as floating windows rather than tabbed windows.
