This question already has an answer here:
If I enter
[tag:X] on meta.stackoverflow.com, it is rendered as a link to tag
X on stackoverflow.com.
Similarly if I post
[tag:X] on chat, it is interpreted as a link to that tag on the SE site associated with that chat room.
I would like to be able to link to a tag on any SE site, not necessarily the one associated with that chat room. E.g. I would like to be able to include python in a chat message associated with another site such as unix.stackexchange.com and have it link to the corresponding tag wiki in stackoverflow (not unix.)
As far as I know the closest you can get at the moment is
<kbd> elements inside links (e.g.
python) but that does not work in chat and does match the style of "real" taglinks.
Any chance of extending the markup syntax to permit this?
