This is actually a version of a problem that comes up frequently -- how to
concatenate a variable or transclusion into a string.
This:
tags="Task <<thisContext>>"
will not work. It won't create a string with "Task" and the value of
<<thisContext>> >
This is called concatenation. If you look for "concatenation" on
TiddlyWiki.com there's at least one howto. Unfortunately, it's not the word
that automatically springs to people's heads.
The two main ways around this problem is to use either {{{ }}} notation
with a addprefix/addsuffix filter operator, or to use a helper macro.
Macro's have substitution variables. A variable for a passed parameter
looks like $variable$ and a substitution variable for an environmental
variable looks like $(variable)$.
So, at the top of your tiddler create a macro like this:
\define thebutton()
<$button>
<$action-sendmessage $message="tm-new-tiddler"
title="Task"
tags="Task $(thisContext)$"
priority="3"
/>
New Task for <<thisContext>>
</$button>
\end
Then, down below replace the existing button code like this:
<<theButton>>
