Playing with URL protocol handlers

[TonyM]

Hi Folks,

I have just being studying URL Protocol handlers such as file: and https:

I am able to define my own such as fred: such that fred:anything opens a desktop app or batch and passes the full address as a parameter.

Can anyone tell be how I may configure tiddlywiki to permit the fred protocol to open like a link beginning with http because at the moment tiddlywiki thinks I am naming a tiddler.

My browsers already know this protocol because it is defined on my windows 10 desktop, I just need to get tiddlywiki to pass it through.

Regards

Tony

Actually this may not be necessary, although it would be tidy

Placing the link into a html href seems sufficient to delegate the protocol to the one defined on my computer

<a href={{!!alink}}>Link to Protocol</a>

where the field alink = 

fred:test:more?here#there

Regards
