I mistakenly did marker folding to my .vimrc:

{{{8 #CS
something..
}}}8  
{{{9 #Math
...
}}}9  
... many more!

I need to switch the format to “#SOMETHING {{{NUMBER” like:

#CS {{{8 
something..
}}}8  
#Math {{{9 
...
}}}9  
... many more!

What is wrong in the following code:

:%s$/({{{\d/) /(#[:alpha:]/)$\2 \1$g

[Solution]

%s$\({{{\d\) \(#[[:alnum:]]*\)$\2 \1$g

    You forgot to escape the parentheses, and the POSIX character classes are only valid within a character class [[:alpha:]]:

    :%s$/\({{{\d/\) /\(#[[:alpha:]]/\)$\2 \1$g
    

    Note, however, that your example text doesn’t contain any slashes – is this what your sample text is actually like?

    The above regex changes this

    /{{{8/ /#A/
    

    To this

    #A/ {{{8/
