What is the symbol used in the Junos CLI to display available commands?

In the Junos CLI, the question mark symbol is used to display available commands. When entered at the command prompt, the question mark provides a list of commands that are relevant to the current context or the command you are typing. This feature is particularly useful for users who may not be familiar with all the commands or syntax available in Junos, as it enables them to explore their options interactively without needing to refer to external documentation continuously.

This functionality enhances user experience and efficiency by allowing quick access to command syntax and options, making it easier to construct valid commands with the correct parameters.
