Using Structured Selection

Structured Selection lets you quickly select Java code in a syntax-aware way.

To use Structured Selection:

• In a Java editor, (optionally) select some text and press Ctrl+Shift+Arrow Up or select Edit > Expands Selection To > Enclosing Element from the menu bar.
• The current text selection is expanded to the inner-most syntax element (more precisely, Abstract Syntax Tree node) that encloses the selection.

When a statement or a list of statements is selected, you can press Ctrl+Shift+Arrow Left or select Edit > Expands Selection To > Previous Element, which will expand the selection with the statement (if any exists) that is immediately before the selected statements.

Pressing Ctrl+Shift+Arrow Down or selecting Edit > Expands Selection To > Restore Last Selection from the menu bar lets you restore the previous structured selection.
