如何用markdown写微信或邮件

在chrome和firefox浏览器中安装extension "Markdown Here"
在微信后台写或者粘贴markdown文本，然后"ctrl+alt+M"，文本就会变成渲染后的markdown 格式。
如果需要编辑，就重复"ctrl+alt+M"，然后文本会取消渲染效果，然后继续编辑，重复快捷键去渲染。直接发布就可以了。

值得注意的是：

微信后台似乎不支持数学公式直接居中的表达，比如 $$ f(x）=x^2+1$$，而其他的一些编辑器支持。比如sublime text 2 + pandoc，或者markdown preview to html等。
所以可以直接在sublime text写好之后，用pandoc 转成pdf，或者直接用markdown preview "ctrl+alt+M" 去查看渲染之后的效果。可以支持修改文件，然后refresh html去查看。
写书也挺适合用markdown的，可以直接用pandoc转成许多其他格式，比如epub等。
还可以直接写latex文档，以及latex slides 等等。

How to set up pandoc shortcut in sublime text 2

install pandoc

Suppose you have installed the package control in ST2, then "Command+Shift+P" or "tools > Command Palette" will pop out the dialog.
type "install packages"
type "pandoc", choose the most general one just with this name.

create short cut

In a normal way, you can just open "command palette" by "cmd+shift+p", and then type "pandoc", then type "PDF" or any other format you like.
Creating shortcut can help you save the typing "pandoc":

Preferences > Key binding users
Add { "keys": ["ctrl+alt+p"], "command": "pandoc"} in to the file.

For example, after adding, my files looks like:

[  { "keys": ["ctrl+alt+m"], "command": "markdown_preview", "args": {"target": "browser", "parser":"markdown"} }  ,  { "keys": ["ctrl+alt+p"], "command": "pandoc"}   ]

Then in your markdown file, you can just use shortcut "ctrl+alt+p" then type "pdf" you can immediately convert it to pdf.

Installation :

Using Package Control (Recommended)

For all Sublime Text 2/3 users we recommend install via Package Control.

Install Package Control if you haven't yet.
Use cmd+shift+P then Package Control: Install Package
Look for Markdown Preview and install it.

To preview :

optionally select some of your markdown for conversion
use cmd+shift+P then Markdown Preview to show the follow commands (you will be prompted to select which parser you prefer):

Markdown Preview: Preview in Browser
Markdown Preview: Export HTML in Sublime Text
Markdown Preview: Copy to Clipboard
Markdown Preview: Open Markdown Cheat sheet

or bind some key in your user key binding, using a line like this one: { "keys": ["alt+m"], "command": "markdown_preview", "args": {"target": "browser", "parser":"markdown"} }, for a specific parser and target or { "keys": ["alt+m"], "command": "markdown_preview_select", "args": {"target": "browser"} }, to bring up the quick panel to select enabled parsers for a given target.
once converted a first time, the output HTML will be updated on each file save (with LiveReload plugin)

Note:

If you want to set the keymap, just " preference> package setting> key bindings - user, and note to use the argument as above.

Then it is really convenient for you to use.

How to make sure "alt+z" is for typing Greek Omega in visual studio code

Just click preference of vscode and then in the json file, add:

{ "key": "alt+z", "command": "-editor.action.toggleWordWrap",
"when": "editorTextFocus" }

in the keybinding.json.

This is from: https://code.visualstudio.com/docs/customization/keybindings

Removing a specific key binding rule

You can write a key binding rule that targets the removal of a specific default key binding. With the keybindings.json, it was always possible to redefine all the key bindings of VS Code, but it can be very difficult to make a small tweak, especially around overloaded keys, such as Tab or Escape. To remove a specific key binding, simply add a - to the command and the rule will be a removal rule.

Here is an example:

// In Default Keyboard Shortcuts  ...  { "key": "tab", "command": "tab", "when": ... },  { "key": "tab", "command": "editor.emmet.action.expandAbbreviation", "when": ... },  { "key": "tab", "command": "jumpToNextSnippetPlaceholder", "when": ... },  { "key": "tab", "command": "acceptQuickFixSuggestion", "when": ... },  { "key": "tab", "command": "acceptSelectedSuggestion", "when": ... },  ...    // To remove the second rule, for example, add in keybindings.json:  { "key": "tab", "command": "-editor.emmet.action.expandAbbreviation" }
