Display clicked tag as a title

Here's what I have. The usual list of tags for a post using:

{{ entries:listing folder="journal" limit="10" taxonomy="true" }}
.
.
.
{{ if tags }}
  {{ tags sort_by="name" }}
    <h5 class="tag"><a href="/journal/tags/{{ name|slugify }}">#{{ name }}</a></h5>
  {{ /tags }}
{{ /if }}
.
.
.
{{ /entries:listing }}

If I click one of the tags, how can I display the clicked tag as a title in the taxonomies.html template?
