To save time, IOS commands may be partially entered and then completed by typing which key or key combination?
In IOS (Internetwork Operating System) command-line interface, the key or key combination that can be used to save time by partially entering commands and then completing them is the Tab key.
When you start typing a command or a part of a command and press the Tab key, the IOS CLI will try to autocomplete the command for you. It will either fill in the remaining part of the command if there is only one option, or it will show you a list of options that match the entered characters.
For example, if you want to enter the “show” command, you can type “sh” and then press the Tab key. The CLI will complete the command as “show”. If you want to enter a command that starts with “config”, you can type “conf” and then press the Tab key to see all the available options like “configure”, “configure terminal”, etc.
Using the Tab key for command completion can save time, especially when working with complex commands or when you are unsure of the exact command syntax. It helps to speed up the command input process and reduce the chances of making typographical errors.
