[href://?;node_id=172086#room|room] is lots of typing compared to  [id://172086#room|room] which should just work, there is no ambiguity, node numbers are always numbers :)

old  [href://?;node_id=172086#room|room] room

new  [id://172086#room|room] [id://172086#room|room]

What shortcuts can I use for linking to other information?

I thank you
