The link Using Keyboard Sequences to Move Around and Edit the Junos CLI is a page from the 11.1 Junos documentation that lists the CLI shortcuts.
Some that I use often:
- Move cursor to the beginning of the command line (Ctrl+a)
- Move cursor back one word (Esc+b or Alt+b)
- Move cursor forward one work (Esc-f or Alt+f)
- Delete all characters on the command line (Ctrl+u or Ctrl+x)
- Delete all characters after the cursor (Ctrl+k)
What shortcuts do you use?
