In this emacs article, let us review the following 7 Emacs navigation options.
- Line navigation
- Screen navigation
- Word navigation
- Special navigation
- Paragraph navigation
- Search navigation
- Navigation from command line
If you don’t have an emacs editor, install emacs editor as we discussed earlier.
Notation used in this article:
- C-a : Ctrl-a
- M-a : Meta-a ( If you don’t have Meta key, use Esc key )
- C-M-a : Ctrl-Meta-a
1. Emacs Line Navigation
Following four navigation can be done line by line.
- C-p : go to previous line
- C-n : go to next line
- C-f : go forward one character
- C-b : go backward one character
By using the repeat factor in EMACS we can do this operation for N times. For example, when you want to go down by 10 lines, then type C-u 10 C-p
Within a line if you want to navigate to different position, you have following two options.
- C-a : go to the starting of the current line.
- C-e : go to the end of the current line.

Nice tips. Some of these navigations options (line, word and search) are also accepted in Bash, to navigate interactively. It will works if the environment is set to use Emacs keystrokes (set -o emacs).
