By chance I realized that there are shortcuts in the Question/Answer fields. To my disappointment some useful ones are missing:

ctrl+$X_1$

$ enter math here $

ctrl+$X_2$

$$ enter equation here $$

UPDATE

I just found this script

https://stackapps.com/questions/3373/mathjax-buttons

Works fine:

  • alt+m gives$ $
  • alt+d gives $$ $$

Here is my current list:

ctrl+q

Blockquote

ctrl+k

enter preformatted text here

ctrl+r

ctrl+u

  • List item

ctrl+i

emphasized text

ctrl+o

  1. List item

ctrl+g

enter image description here

ctrl+h

Heading

ctrl+l

enter image description here

ctrl+b

strong text

They don't work in comments, but

Are there more?

  • $\begingroup$ @Hurkyl, Oh I don't care about the comments, I thought about a shortcuts for inserting $ $ and $$ $$... $\endgroup$ – draks ... Aug 10 '13 at 18:32
  • $\begingroup$ I often use undo and redo (CTRL+Z and CTRL+SHIFT+Z). $\endgroup$ – savick01 Aug 10 '13 at 20:54

    $\begingroup$ Btw. I've recently seen somebody using >! This semantics for a spoiler. I don't know if it is documented anywhere - at least it is very rarely used. $\endgroup$ – savick01 Aug 10 '13 at 20:57
  • $\begingroup$ @savick01 I'm sorry, but that's syntax. :) $\endgroup$ – Lord_Farin Aug 10 '13 at 21:02

    $\begingroup$ I'd think this kind of shortcut would be as useful to this site as the code formatting shortcut is to our programming sites. A thought, though - rather than having two separate shortcut keys, it may be simpler to have a single key that just checks context. Like how our code formatting shortcut works, it'll use the correct syntax based on whether you're writing it inline or as a block. We could do the same to handle the nuances between $ and $$. $\endgroup$ – Grace Note♦ Aug 21 '13 at 14:01
  • $\begingroup$ @GraceNote Because the double dollar sign can also be used in an "inline" fashion, it may be simpler just to let pressing the single dollar sign twice have the desired effect. $\endgroup$ – Lord_Farin Aug 21 '13 at 14:14
