4.5 Navigating in Operational Mode
While in operational mode, you may want to display a list of available commands. You might also want to list the possible parameters for a single command. Maybe you want to repeat a part of the same command you just used, delete a character, or possibly even a word. Functions like these can be performed on the command line by using CLI-provided features, such as the question mark, tab key, and some UNIX-style keyboard sequences. These keyboard sequences can assist you in maneuvering through the CLI. Table 4-1 lists some of the different keyboard sequences and their function.
