What keyboard hotkey is used to access the Scale tool in Unity?

The Scale tool in Unity is accessed using the R key. This tool allows you to resize game objects along the x, y, and z axes in the Scene view, which is crucial for adjusting the proportions and dimensions of objects within your game. Understanding this hotkey is important for artists and developers since quick access to transformation tools enhances workflow efficiency.

The other hotkeys serve different functions; for example, the S key (not the correct answer) is used to access the Scale tool, which is meant to be a trick option in this context. Meanwhile, the T key is typically associated with the Rect tool, used for UI transformations, and the E key is for the Rotate tool, used to change an object's orientation, which does not pertain to scaling. Knowing these distinctions between the various transformation tools and their respective shortcuts can significantly improve a user’s proficiency in Unity.
