> I would like to enable this syntax:
>    [[WikiPage"Tooltip title"]] displays WikiPage
>    [[WikiPage"Tooltip title"|link text]] displays link text
>    [[WikiPage"Tooltip title"|+]] displays the title of the page
>    [[WikiPage"Tooltip title"|#]] a number/reference

>    http://site/picture.jpg"Tooltip title"
>    http://site/picture.jpg"Tooltip title" | caption text
>    Attach:picture.jpg"Tooltip title"
> 2. This would be consistent with the markup for external links, InterMap links

>    [[http://pmwiki.org"Tooltip title"|link text]]
>    [[Wikipedia:Free_Software"Tooltip title"|link text]]
>    [[mailto:address at example.com"Tooltip title"|link text]]
>    [[Attach:file.zip"Tooltip title"|link text]]
>    Titles for external links were captured and processed in this format since
>    2006, but were not displayed in the default installation, although this was
>    documented and admins could enable it in config.php. Version 2.2.14, 
>    released 20 months ago, started displaying the tooltip titles by default.
> 3. Also since 2006, PmWiki captures the "..." part in internal links like a 
> tooltip title, but instead of using it for a tooltip title, it keeps it in the 
> link text (not in the link target page, [[Page"Tooltip title"]] links to 
> [[Page]]). Fixing this would require only a few minor changes.
> These are the reasons to adopt the [[WikiPage"Tooltip title"]] markup: 
> consistency with other tooltip markups, easy to implement, unlikely to break 
> existing wikis.
> There is a reason why not to implement it this way, notably PmWiki.RoadMap 
> suggests the format [[Link|text|title]]. In a previous discussion,
> * 3 users+Pm preferred that format
> * 5 users preferred [[Link"Title"|text]] : 
>   http://thread.gmane.org/gmane.comp.web.wiki.pmwiki.user/24697
> So I'd like to know what do you think about this feature. Note that 
> implementing it will not break existing wikipages - internal link titles never 
> worked - but it will allow future improvements of accessibility for those who 
> need it.

Hi, Petko,

I can't really see how this small and consequent change warrants such a
detailed write-up :)  Just go for it!

If quotes weren't already used for external links and images, I would be
in favour of [[Link|text|title]] (which feels like a logical extension to
current link markup). But since quotes are already used for this...
