### Intimidated?
. . .
- Decades of history.
- Bazillion tutorials.
- _Opinionated_ views.
\smallskip
. . .
### But fear not!
. . .
- _Incremental use_ works.
- Learn a few steps. Master them.
- Learn some more.

### A really good \alert{builtin} resource
\medskip
. . .
- The Emacs Tutorial
- just hit `C-h t`
- ie type `Ctrl` _and `h`_, then type `t`.
- Covers a lot of the basis
- Worth spending some time with
- And revisiting

## Emacs: Editing
### Key Advantages
. . .
- Particular uses _carry from one mode to another_ for (essentially)
all forms of text
- There are too many to enumerate but ...
- ... (maybe my) favourite example
- `C-space` to mark a starting
- Navigate to end
- `M-x comment-region` will uncomment the regions
- In \alert{any programming language} or \alert{text format}
- Also cool: Prefix the same with `C-u` ("undo") to uncomment
## Emacs: Editing
### More Key Advantages (via Somewhat Random Personal Selection)
. . .
- Indentation is always sensitive to the programming language
- `M-q` formats ("flows") indents a paragraph
- `C-M-\` indents a region in the current language
- Very powerful 'undo' feature
- Rectangular regions (could be a five-mi presentation in itself)
- 'Record' key sequence to 'replay' for ad-hoc automation (ditto)
- Named Register to hold paste-able content or positions (ditto)
