Bram Chen 48a98bad02 Revise the last changes for "Linking in WikiText" (#3083)
`[[Open file|c://users/me/index.html]]` is a wrong syntax for linking in wikitext.

`c://users/me/index.html` is not even a valid URI, although `[ext[Open file|c://users/me/index.html]]` works with Google Chrome and Microsoft Edge on Windows 10.

`[ext[Open file|c:\users\me\index.html]]` works with Chrome, Edge and Firefox on Windows 10.

title: Linking in WikiText
type: text/vnd.tiddlywiki
A key capability of WikiText is the ability to make links to other tiddlers or to external websites.
! Manual Links
Link to a tiddler by title:
```
[[Tiddler Title]]
```
To link to a tiddler and specify the text of the link:
```
[[Displayed Link Title|Tiddler Title]]
```
You can also create a link from the editor toolbar. Click ''link'' ({{$:/core/images/link}}), and search and select a tiddler.
! ~CamelCase Links
For tiddler titles that match the CamelCase rules, just typing the title without double square brackets will automatically create a link.
You can suppress a link from being recognised by preceding it with `~`. For example:
<<wikitext-example src:"* ~HelloThere is not a link
* ~http://google.com/ is not a link">>
! External Links
To link to an external [[resource|https://en.wikipedia.org/wiki/Web_resource]] such as a website or a file, type its //full// [[URL|https://en.wikipedia.org/wiki/URL]], including the [[URI scheme|https://en.wikipedia.org/wiki/URI_scheme]] such as a protocol (e.g. `http://`, `file://`) or `mailto`:
```
https://tiddlywiki.com/
[[TW5|https://tiddlywiki.com/]]
[[Mail me|mailto:me@where.net]]
[[Open file|file:///c:/users/me/index.html]]
```
For this syntax to work, the URL has to be recognisable as a URL. Otherwise, it is treated as a tiddler title. As a result, in case you want to link to a resource locatable using a relative path, use the extended syntax:
```
[ext[Open file|index.html]]
[ext[Open file|./index.html]]
[ext[Open file|../README.md]]
[ext[Open file|c:\users\me\index.html]]
```
The extended syntax still works with full URLs, although in that case it is not necessary:
```
[ext[https://tiddlywiki.com]]
[ext[TW5|https://tiddlywiki.com]]
[ext[Mail me|mailto:me@where.net]]
[ext[Open file|file:///c:/users/me/index.html]]
```
You can also use the extended syntax to force an external link:
```
[ext[Donate|bitcoin:1aabbdd....?amount=0.001]]
```
! Customising Tiddler Links
See the LinkWidget for details of the underlying widget used to implement tiddler links, including macros that can be used to customise its behaviour.
