Hi Naoh, i am using syntax highlighter plugin. But the user have to manually type like [code=sql] select * from emp [/code]. But the problem there is no way on this editor to inform the user how to add code. For instance, stackoverflow editor gives to hint how add code,links etc.
Another solution will be to add an icon for code on the existing q2a editor.
Also, i would like to know whether its possible to replace this ckeditor with jcedtor or other open source editor.
