You can use the mouse to drag and drop text in the Story Editor or in the Layout View. You can even drag text from the Story Editor to the layout window (or vice versa), or into some dialog boxes such as Find/Change. Dragging the text from a locked or checked-in story copies the text rather than moves it. You can also copy text or create a new frame when dragging and dropping text.
If the text you drop doesn’t have the proper spacing, select the Adjust Spacing Automatically option in Type Preferences.
