Ship mechanics are the core of the game. i often drag and drop to merge ships and build a fleet.
Clicking to merge ships lets you start, and you trade with cities to gather resources.
No extra buttons or toggles are stated.
Quick tip i discovered: Merge ships early to boost your fleet power then trade often to gather more resources. This uses the drag-and-drop mechanic from the description to build a stronger fleet.
