What keys can be used to stop a process after initiating the Format Painter?

Using the Esc key is a valid way to stop the Format Painter process after it has been initiated. The Format Painter tool allows users to quickly copy formatting from one cell and apply it to another. However, if you decide to cancel this action after starting it, pressing the Esc key will effectively terminate the Format Painter.

This action is common in various software applications, where the Esc key is used as a general cancel command. In the context of Excel, once you have activated the Format Painter, the tool remains active until you either apply the formatting or cancel the operation, which can conveniently be done by pressing Esc.

In contrast, other options, such as Ctrl + Z, would attempt to undo an action, but they are not intended to specifically cancel the Format Painter operation in real-time. Ctrl + C is used to copy content, and Alt + F4 is typically used to close the application entirely, neither of which are suitable for stopping the Format Painter once it has been activated.
