missing Find symbol/engines/"output web apps" list

[4www]

In the case of a user starting to type in their omnibox, and wanting to "complete an action", such as ex:

• would like to convert a/this file in an other fomat
• would like to CRUDSearch information somewhere,
• generally accessing a web app, and maybe getting a "url pipeable output"
• etc.

some pattern of missing engines, symbols and semantics emerge, can try to list them until we find an app that provides the desired functionalities.

Maybe can also be discussed on:

• https://github.com/internet4000/find/discussions/
• https://matrix.to/#/%23i4k-find%3Amatrix.org

Some examples

• https://en.wikipedia.org/wiki/Tag_URI_scheme
• MSC2312: Matrix URI scheme proposal matrix-org/matrix-spec-proposals#2312
  matrix also uses prefix symbol similar to find to represent rooms(id,alias), users, events:

The following classes MUST be supported:
User IDs (@user:example.org)
Room IDs (!roomid:example.org)
Room aliases (#roomalias:example.org)
Event IDs ($eventid:example.org)

• view-source: from mobile browsers polyfill; see possibilities with https://eruda.liriliri.io/
• magnet: links protocol (to do something by default? browsers already request for selecting an application for this scheme, but could think about "registering a protocol handler")
• magnet link utilities (to .torrent, decrypt etc.)
• data:<mediatype>[;base64],<data> as a protocol/symbol, and not a set of + do actions
• and other URI/protocol/scheme that one might copy/paste to a URL or want to "transform into an other URL/protocol" https://en.wikipedia.org/wiki/List_of_URI_schemes
• also would be nice to be able to even "list links" that can "resolve to something in a browser", for applications like dns:[//<host>[:<port>]/]<dnsname>[?<dnsquery>]
• dns://radio4000.com/A/ -> dns://radio4000.com/A/ (not rendered in github markdown, but would be in html)
