sorry, I re-read my post and it doesnt seem particularly clear ??
I had read the permalinks codex entry before, but it deals with hiding the underlying parameter query. I dont want to hide it at all – I simply want to change the parameters’ name and accepted values.
For example: the default structure is https://www.example.com/?p=423 for posts, and for Pages, it’s https://www.example.com/?page_id=26
I want to change this so for example post links are https://www.example.com/?news=423, and pages come up as https://www.example.com/?page=about (the parameter being changed from their post ID to their post slug).
I hope that’s slightly clearer ??
