Duplicate Line or Selection

Edit | Duplicate Line or Selection

One of the ways of creating a code element similar to an existing one (e.g. a new method overload or a new auto-implemented property) is cloning the existing element with copy-paste and then editing the clone.

JetBrains Rider helps you streamline the cloning part — with a single keystroke (Ctrl+D) the cloned code is inserted right after the original.

To quickly duplicate the current line or selection

  1. If you want to clone a line, set the caret at this line line. To clone an arbitrary piece of code, select it in the editor.

    To select a logical code block, press Ctrl+Alt+Right one or more times.

  2. Press Ctrl+D or choose Edit | Duplicate Line or Selection from the main menu. Alternatively, you can press Ctrl+Shift+A, start typing the command name in the pop-up, and then choose it there.

  3. The duplicated line or multi-line selection is inserted below the original line or selection; the duplicated inline selection is inserted to the right of the original.

  4. If you have duplicated a selection, the selection stays at the clone. If necessary, you can press Ctrl+Shift+Alt and then use arrow keys to move the clone to the desired position.
