## org.eclipse.ui.texteditor
Class InsertLineAction

    java.lang.Object
      org.eclipse.jface.action.Action
          org.eclipse.ui.texteditor.ResourceAction
              org.eclipse.ui.texteditor.TextEditorAction
                  org.eclipse.ui.texteditor.InsertLineAction

All Implemented Interfaces:
  IAction, IUpdate

public class InsertLineAction
extends TextEditorAction

This action implements smart return. Instead of breaking the line where we are, we do the following:

Smart Enter

- if the caret is on a line containing any non-whitespace, a line is inserted below the current one and the caret moved to it,
- if the caret is on a whitespace-only line, a line is inserted below the current line, but the caret stays in its position.

Smart Enter Inverse

- if the caret is on a line containing any non-whitespace, we insert a line above the current one and move the caret to it (i.e. it stays at the same offset in the widget),
- if the caret is on a whitespace-only line, a line is inserted above the current line, but the caret stays in its logical position (i.e., it gets shifted one line down in the document, but keeps its position relative to the content following the caret).

Since:
  3.0

Field Summary
`protected boolean` | `fAbove` `true` if this action inserts a line above the current (Smart Enter Inverse), `false` otherwise
