Add, delete, and manipulate lines

Normally you press Enter to start a new line when the caret is at the end of that line, but you can also start a new line if the caret is in the middle of a line.

To add a new line below the current line, press ShiftEnter.

Instead of starting an empty line, you can duplicate an existing line and edit it as required.

To duplicate the current line, press Ctrl0D.

One way to delete a line is to select the whole line and press Delete or Backspace, but a slightly more efficient way is to press Ctrl0Y when the caret is anywhere in that line.

You can move the node under caret or a group of selected nodes up and down in their containing collection of nodes using dedicated shortcuts: CtrlShift0↑ and CtrlShift0↓.

If no shortcuts are assigned to these actions in the currently selected keymap, you can assign your own shortcuts to the Move Line Up and Move Line Down actions in the Keymap page of the IDE settings  CtrlAlt0S.
