• [nitpick] There's an inconsistency in the label references: the window is identified with 'prodname_copilot_chat_short' while the icon uses 'prodname_copilot_chat'. If they refer to the same feature, please standardize the naming for clarity.

Open the {% data variables.product.prodname_copilot_chat_short %} window by clicking the **{% data variables.product.prodname_copilot_chat %}** icon at the right side of the JetBrains IDE window.
