So what we have so far is ...

A way to open direct to a recipe page via a recipe id

And

A way to open the professions page from a hyperlink.


What we need now is a way to find out the recipe id from a recipe link which hopefully will be figureoutable from this page : https://warcraft.wiki.gg/wiki/Hyperlinks

Ah never mind, looks like the recipe links are either item links or enchant links.

Looking at the tradeskill window itself, it only allows people to link their whole profession not a recipe, so you might only be able to open to a particular recipe page using a known recipe ID. Unfortunately the only way I could see to get both a recipelink and recipeid automagically was by reading the recipes from the tradeskill page.

The last known recipe in my example was the Enchant Vellum I could craft with my Inscription Gal.
The recipe ID for it is 52739 but none of the numbers in the Enchant Vellum recipe link contains that number. Instead it has 38682 which is the actual item id and 70:266 which I assume is the player level and specialization id who provided the link and the next numbers that appear are 1:3524 which don't provide any clues to me but could be the number of bonsuses and a bonus id - if I am reading the info on https://warcraft.wiki.gg/wiki/ItemLink correctly.

Anyway, this is my last attempt, and is the best I could do using both the info Fizzle provided and what I tracked down and hopefully gets you part way at least.
