How to Edit

How to Format
-
create code fences with backticks ` or tildes ~
```
like so
``` -
add language identifier to highlight code
```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line
- to make links (use https whenever possible)
<https://example.com>
[example](https://example.com)
<a href="https://example.com">example</a>
How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. windows-7), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
Dif I wanted to, but since I don't have a common need for this, all I have to type isM-x *ded RETand bam–done. (If I did indeed have to type this every time, you're absolutely right that it'd be absurd – luckily that's not the case.)M-x *ded REThave any significance or is it random? If the latter, how do you keep track of all the shortcuts you've assigned inemacs? Does memorisation suffice or do you find yourself having to look them up?*dedis an abbreviation for the full function name*-delete-empty-directories. Many completion engines (such as ivy, the one I use) understand this kind of fuzzy matching. As for keeping them memorized… I simply don't have to. The functions I've defined all start with*so I can easily find them if they're not bound to a key. Otherwise, emacs itself will tell me if there was a faster way of calling the function. If all else fails, there's alwaysapropos.
