    | Windows   | <kbd>Alt + 255 or ANDnbsp;</kbd> |

1. `Text Underlined with - or =  is header`
    H1, H2... (hash, 2xhash,... at line beginning), H2 with equal signs in next line is H1, H2 with minus signs in next line is H3.

1. Ignoring Markdown formatting: by using \ before the Markdown character. Eg
    Let's rename \*our-new-project\* to \*our-old-project\*.  
    Same without \ :  Let's rename *our-new-project* to *our-old-project*.

   `Code inline : 1 backtick (altgr+7) around string or 4 spaces idented - in this list does not work`  
   **Code block**: fenced by lines with three back-ticks eg three altgr+7php ...SOME CODE...  three altgr+7, or four blanks idented (at line beginning) - in this list does not work or `<kbd>some_txt</kbd>`
   ```php
   <?php
   // blah, blah
   echo 'blah, blah' ;
   echo '<pre>blah='; print_r('blah, blah'); echo '</pre>';
   ```
   Code blocks are part of the Markdown spec, but **syntax highlighting isn't**. Many renderers like **Github's and Markdown Here** support syntax highlighting. Which languages are supported and **how those language names should be written** vary from renderer to renderer. **Markdown Here** supports highlighting for dozens of languages (and not-really-languages, like diffs and HTTP headers); to see the complete list, and how to write language names, see the **highlight.js demo page** http://softwaremaniacs.org/media/soft/highlight/test.html .

# <a name="Emphasis"></a>2. Emphasis

**Italics** (Emphasis):       *asterisks* or _underscores_ 
`*asterisks*` or `_underscores_` (backticks = print as is)

**Bold** (Strong emphasis), with **asterisks** or __underscores__:
`**asterisks**` or `__underscores__`

**Combined** emphasis with **asterisks and _underscores_**:
`**asterisks and _underscores_**`

**Strikethrough** uses two tildes. ~~Scratch this.~~:
`~~Scratch this.~~`

# <a name="Lists"></a>3. Lists
1. First ordered list item, has 1.BLANK at begginning - others can have same 1. 
1. Another item - actual numbers don't matter, just that it's a number
   - **1 (or 2) LEADING SPACES = sub-list**
   - Unordered list use **asterisk BLANK  or minuses  or pluses** instead 1.BLANK
1. Third item  
    * 2 LEADING SPACES = sub-list
    * 2 LEADING SPACES 
1. And fourth item

To have a line break within same paragraph, use 2 TRAILING SPACES.  
   No effect: 3 LEADING SPACES - Note that this line is separate, but within same paragraph.(2 TRAILING SPACES IN PREVIOUS LINE)  
   This is contrary to the typical GFM line break behaviour, where trailing spaces are not required.  
   
    4 LEADING SPACES renders to HTML code (pre) block tag.
  
Code inline: backticks (`altgr+7`) around string

## Task lists
To create a task list, preface list items with a regular space character followed by [ ]. To mark a task as complete, use [x].

# <a name="Links"></a>4. Links
There are two ways to create links.

[I'm an **inline-style** link](https://www.google.com)

[inline-style link with title](https://www.google.com "Google's Homepage")

[I'm a **reference-style link** ee LINK IS AT SCRIPT END - mozila] [Arbitrary case-insensitive reference text]
[You can use **numbers for reference-style link** definitions - slashdot][1]
Or leave it empty and use the [link text] - reddedit.

[I'm a **relative reference** to a repository file](../blob/master/LICENSE)

URLs and URLs in angle brackets will automatically get turned into links.   
http://www.example.com  and sometimes example.com (but not eg on Github).

Some text to show that the reference links can follow later.

**Here are reference-style links AT SCRIPT END**
[arbitrary case-insensitive reference text]: https://www.mozilla.org

[1]: http://slashdot.org

[link text]: http://www.reddit.com

# <a name="Code"></a>6. Code and Syntax Highlighting
Code blocks are part of the Markdown spec, but syntax highlighting isn't. However, many renderers -- like Github's and Markdown Here -- support syntax highlighting. Which languages are supported and how those language names should be written will vary from renderer to renderer. Markdown Here supports highlighting for dozens of languages (and not-really-languages, like diffs and HTTP headers); to see the complete list, and how to write the language names, see  highlight.js demo page http://softwaremaniacs.org/media/soft/highlight/test.html.

Inline `code` has `back-ticks around` it (AltGr+7).

Blocks of code are either fenced by lines with three back-ticks ```, or are indented with four spaces.

I recommend only using the fenced code blocks -- they're easier and only they support syntax highlighting.

```php
echo MarkdownExtra::defaultTransform(
      file_get_contents("MarkdownCheatsheet.txt")
);
```

```javascript
var s = "JavaScript syntax highlighting";
alert(s);
```
 
```python
s = "Python syntax highlighting"
print s
```
 
```
No language indicated, so no syntax highlighting. 
But let's throw in b (bold).
```

var s = "JavaScript syntax highlighting";
alert(s);

s = "Python syntax highlighting"
print s

No language indicated, so no syntax highlighting in Markdown Here (varies on Github). 
But let's throw in a .
# <a name="Tables"></a>7. Tables

Tables aren't part of the core Markdown spec, but they are part of GFM and Markdown Here supports them. They are an easy way of adding tables to your email -- a task that would otherwise require copy-pasting from another application.

Colons can be used to align columns.

| Tables        | Are           | Cool  |
| ------------- |:-------------:| -----:|
| col 3 is      | right-aligned | $1600 |
| col 2 is      | centered      |   $12 |
| zebra stripes | are neat      |    $1 |

There must be AT LEAST 3 DASHES SEPARATING EACH HEADER CELL.
The outer pipes (|) are optional, and you don't need to make the raw Markdown line up prettily. You can also use inline Markdown.

Markdown | Less | Pretty
--- | --- | ---
*Still* | `renders` | **nicely**
1 | 2 | 3

<a name="blockquotes"></a>
# 8. Blockquotes
> Blockquotes are very handy in email to emulate reply text.
> This line is part of the same quote.

Quote break.

> This is a very long line that will still be quoted properly when it wraps. Oh boy let's keep writing to make sure this is long enough to actually wrap for everyone. Oh, you can *put* **Markdown** into a blockquote. 
> 
> paragraph 2222 aaaaaaaa gggggggg

# <a name="Videos"></a>12. Videos (Youtube)

Videos can't be added directly, but you can add an image with a link to the video like this:

`<a href="http://www.youtube.com/watch?feature=player_embedded&v=YOUTUBE_VIDEO_ID_HERE
" target="_blank"><img src="http://img.youtube.com/vi/YOUTUBE_VIDEO_ID_HERE/0.jpg" 
alt="IMAGE ALT TEXT HERE" width="240" height="180" border="10" /></a>`

Or, in pure Markdown, but LOSING IMAGE SIZING AND BORDER:

`[![IMAGE ALT TEXT HERE](http://img.youtube.com/vi/YOUTUBE_VIDEO_ID_HERE/0.jpg)](http://www.youtube.com/watch?v=YOUTUBE_VIDEO_ID_HERE)`

[![IMAGE ALT TEXT HERE](http://img.youtube.com/vi/YOUTUBE_VIDEO_ID_HERE/0.jpg)](http://www.youtube.com/watch?v=YOUTUBE_VIDEO_ID_HERE)

*       _ C t r M a i n  is functional name because it is main controller

* WHEN: user enters URL http://dev1:8083/fwphp/glomodul/mkd/
