+ You could use the lisp interpreter to make lists or do some |
| 24 |
+ simple math. Type these in and then type control-x, control-e |
| 25 |
+ with the cursor at the end of them. Watch the minibuffer at the |
| 26 |
+ bottom of the screen. |

+ <p> |
| 35 |
+ Understanding how to navigate the cursor over lists is quite |
| 36 |
+ useful. With the cursor pointed on a [, (, or {, use M-C-f to |
| 37 |
+ go to the end. Use M-C-b to go to the beginning of the list. |
| 38 |
+ That is escape, control-f and escape, control-b |
| 39 |
+ respectively. |
| 40 |
+ </p> |
| 41 |
+ <p>You could load your elisp.</p> |

| 46 |
+ Now, you may want to clean up your code or make replacements in a |
| 47 |
+ function. Click and drag or use control-space to set a mark. |

| 53 |
+ That will toggle the highlighting of selected text. Now, M-% will |
| 54 |
+ prompt you to search and replace or query-replace. Also, |
| 55 |
+ global-font-lock-mode will toggle the syntax highlighting; |
| 56 |
+ indent-region will nicely indent nested code blocks or HTML. A quick |
| 57 |
+ comment comes from M-; or escape-semicolon. |

| 77 |
+ <p>Bash has some keystrokes in common with Emacs. You can search |
| 78 |
+ your shell history with control-r but not control-s. If you try |
| 79 |
+ control-s in bash, it will hide your typing. You can type |
| 80 |
+ control-q to see input to bash again. To cancel a search, type |
| 81 |
+ control-g. Just like Emacs, you can kill text several times with |
| 82 |
+ control-k and get it back with control-y. You can then use |
| 83 |
+ escape-y repetitions. You can suspend Emacs with control-z. Try |
| 84 |
+ the jobs command to see what is suspended. Then type fg or fg 1 |
| 85 |
+ to get back to Emacs.</p> |
