tmux.Window.NewWindow

NewWindow creates a window relative to the receiver's exact winlink. Set Direction to NewWindowDirectionAfter or NewWindowDirectionBefore for non-destructive relative creation. With the zero Direction, tmux targets the receiver's occupied index and normally returns a command error; KillExisting can destroy and replace that target. Attach changes the current window only in that target session. Index is rejected before execution because the receiver already supplies the target position. SelectExisting has no no-output recovery on this exact-target form; tmux must print the created WindowID.
