Smart add tasks with shortcuts?

Is your feature request related to a problem? Please describe.

Not a problem, it's only something I've seen in another app that I like very much and would like to ask if it's on the roadmap for "Tasks".

Describe the solution you'd like

Coming from RTM (rememberthemilk), I inserted my first task in the Nextcloud Tasks interface using "smart add" feature (see https://www.rememberthemilk.com/help/answer/basics-smartadd-howdoiuse ), and noticed that it works for tags: if I write my task description and add a word preceded by "#", it's recognized as a tag.
Questions:

• where is this behaviour described (word with prepended "#" recognized as tags)?
• are there other such "smart add" features (e.g. "^" for due date, "!" for priority, "@" for location, "*" for recurrence,...) already present in Tasks? Which one, and where are they described?
• if importing Tasks from ics, the "DESCRIPTION" field does not consider words with prepended "#" as tags, is there a technical reason for this?

Describe alternatives you've considered

(Painfully) insert all the informations with mouse.
I'm willing to give more info if you want to go down this road, and to test features!

Additional context

No response

The issue names the Tasks interface, smart add behavior, and ICS DESCRIPTION importing but no files, tests, or entry points. Start by checking how task text and ICS descriptions are parsed, then verify which prefixes are supported and documented; done means the behavior and any implementation or documentation scope are clearly established.
