What is the purpose of the GOK command in Linux?

The GOK command in Linux serves as an onscreen keyboard. It is designed to assist users, particularly those with physical disabilities, by providing a graphical interface that allows them to input text and commands using a mouse or other pointing device rather than a traditional keyboard. This functionality is particularly useful in environments where physical keyboard access is limited or impractical. Utilizing GOK, users can navigate through key selections on the screen, enabling them to enter information and interact with the system in a way that is more accessible. The other options address different functions that are not related to the purpose of the GOK command, making it clear why this answer stands out as the correct one.
