So from reading your updated answer and looking at the other question you mentioned I would assume you are trying to create prefixed dynamic links that don't conflict with your routing.
For example site.com/about would link to your about page and site.com/#about would load up your custom template.
Problem
The problem with using a # for your trigger is that really this should be used for linking to internal sections on a page and with the above site.com/#about would actually just link to your index page and if you had a <div> with an id of about you'd find the scroll position at that div, so I think using a # is going to give you a lot of headaches.
Solution
Perhaps use the @ sign? if it's good enough for twitter to use then I don't think you'll have many problems using it.
So, in your config/routes.php you would have:
return array(
'(?P<username>\@\w+)' => '_someCustomTemplate',
);
This will match anything starting with an @, assign it to username a variable in your template and load it up, I tested on the Happy Lager install and it worked like a charm, /about goes to the about page /@about goes to my custom template
So in your custom template you could have the following:
{# This will get rid of the @ #}
{% set username = username|replace({'@': ''}) %}
{% set user = craft.users.username(username) %}
If you want to change the trigger to something else, just change @ in the route expression and then in the replace filter, but that should do the trick for you and avoid conflicts!
on a side note, I replaced @ with a # and it didn't work, just went to the home page
"link" is variable and "ToLeft" and "ToRight" are two different links of type.. Maybe edit the original question with some further clarification? – Brad Bell May 26 '15 at 15:49*loads "_ToLeft" and*loads "_ToRight" template. This would not work. So I think, the special character would actually help here. – Dominik Krulak May 26 '15 at 17:35#author1linkToRightand#author1linkToLeftyou would be able to separate the#author1andlinkTo...parts based on whether it has the special character prefix? So then you'd have two variables,#author1andlinkTo...that you'd be able to use to pull the correct template in? – Alec Ritson May 27 '15 at 15:05
