GNU Emacs Text Editor — Quick Reference
To open the GNU Emacs text editor, either launch it from your
desktop environment's applications menu, or enter the shell
command emacs
at the terminal.
Unusual aspects
- Clicking
- When placing the cursor with the mouse, you click in
the centre of a character, not in between
characters.
- Selecting
- When selecting a region of text, you don't click and
drag. Instead, click with the left mouse button on one
character then click with the right mouse button on
another.
- Prompt
- Take note of the single blank line at the very bottom of
the editor window: this is where commands will prompt you
for input and give you feedback. You can use Ctrl + G to
cancel a command if it is prompting you for input.
