Link shortcuts to support websites [duplicate]

Question

Ok I hope I can express this well:

Often I see comments that tell the OP to e.g. improve the acceptance rate, use proper formatting and such, including a link to How does accepting an answer work? or the editing help or F.A.Q.

How about if the Markdown parser could be extended to include shortcuts like ~edit-help~ or ~accept-answer~ which would be automatically extended to the corresponding links. (Update: Or if the input could be pre-parsed and this shortcuts are turned into Markdown links).

This way, one who is eager to help the community would not have to search or bookmark all the links to the important sites ;)

The list of shortcuts could be editable by high rep users.

Would this be even possible or would this slow down the parsing process too much? Or is it not worth the effort?

What do you guys think?

Included from the comments to make my point more clear:

My point is that there are all kinds of problems new users might have and information or help can be found on different websites or questions on meta. Even if one has bookmarked the howtoask section one still has to copy and paste the link. I just think this is such a common task (for some of us), that it could be made easier for us by, e.g. just typing ~howtoask~ or ~howtoaccept~ and the link gets inserted automatically.

Add data.SE style "magic links" to comments

Answer 2

Note that it's not just the Stack Exchange websites that need to understand the content: all third parties that rely on the API or data dump need to know about SE-specific Markdown enhancements^† too.

Like: spoiler text has been implemented in such a way that renderers that are oblivious about this enhancement can still show it. And tags such as [tag:tag-name] are kind of human readable too when not rendered in any special way?

^{† When adding new things to Markdown, I'd rather see support for footnotes! :-)}
