Is it possible to put tags and category information in the post as text?

Is it possible to put tags and category information in the post area, so one doesn’t have to click the appropriate fields and use the mouse? Ideally I just want to type “#art” “cat:painting” in the text editor and word press automatically assigns these values to the post once I hit “Post”.

There’s a plugin for using hashtags in the post – hashtagger. It will override the normal way you’d add tags which has caused confusion for some of my users but it works.

You can also look at the process around creating tags/posts via shortcode through the Jetpack post via email option.
