Spacemacs

Awesome a bit unknown commands:

• SPC f s: save
• SPC f f: create/open a file
• SPC r l: helm resume (start at the latest projectile-find-file for example)
• SPC s l: resume-last-search
• g c c: comment out a line
• SPC r y: show previous yanked things
• SPC /: find in all project
• SPC *: find word under cursor in all project
• C-o: Jump back
• "ay: to yank into register a, then "ap to paste

Level 1 in org-mode

This is a text I write so we can test many different details of a web page. The text can be bold, italic, strikethrough or keyword.

Here is a link to another page.

There should be whitespace between paragraphs.

Multiples lines in the source code should be set as a single paragraph. But if I use a double space There should be a forced newline.

Width

Testing the width: I use a max width of 71

Math

Let also try to write some math inside the text $\pi_1(X,x_0)$. In the middle of the text again$x$ and $x_i\times 0$.

$x^y / \log(x)$

$\prod_{i=0}^n \sum_{x_i\in E} \frac{1}{x_i}$

Examples

This is an example.
We can say a few things.
Perhaps a list:

- thing
- another thing

Lists

Ordered lists

1. counting with very very long lines. Just to check that everything is all right regarding very long lines inside list, but also nested lists.
2. foo
3. bar
4. baz
5. counting
6. up
7. to
8. a
9. big
10. number enough
11. to have two
12. digits
13. The simplest example of a homotopy group is the fundamental group of a space, which is written $\pi_1(X,x_0)$: Given a space$X$ and a point$x_0$ in it, one can make a group whose elements are loops at$x_0$ (continuous paths from$x_0$ to $x_0$), considered up to homotopy, with the group operations given by the identity path (standing still), path concatenation, and path reversal. For example, the fundamental group of the 2-sphere is trivial, but the fundamental group of the torus is not, which shows that the sphere and the torus are not homotopy equivalent. The intuition is that every loop on the sphere is homotopic to the identity, because its inside can be filled in. In contrast, a loop on the torus that goes through the donut's hole is not homotopic to the identity, so there are non-trivial elements in the fundamental group.
14. Lot of things.
