Duplicate line or selection
One of the ways of creating a code element similar to an existing one (for example, a new method overload or a new auto-implemented property) is cloning the existing element with copy-paste and then editing the clone.
ReSharper helps you streamline the cloning part — with a single keystroke Control+D the cloned code is inserted right after the original.
Duplicate the current line or selection
If you want to clone a line, place 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 Control+W one or more times; to select the current declaration, press Control+Shift+[.
Press Control+D or choose from the main menu. Alternatively, you can press Control+Shift+A, start typing the command name in the popup, and then choose it there.
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.
If you have duplicated a selection, the selection stays at the duplicate. If necessary, you can press Ctrl+Shift+Alt and then use arrow keys to move the duplicate to the desired position.
