I'm trying to get a line produced by tikzmarknodes to start and end with little hooks, i.e., horizontal thinner lines protruding from the ends, more or less to resemble a bracket. I couldn't figure out how to manipulate the node code.

This is some text and tikzmarknode{a}this is some text.



This is some text and tikzmarknode{b}this is some text.

begin{tikzpicture}[remember picture]  draw[overlay,semithick] (a.west) -- (b.west); end{tikzpicture}



This is some text and begin{tikzpicture}draw[overlay,very thin] (0.05,0.1) -- (0,0.1); draw[overlay,semithick] (0,0.1) -- (0,-0.35); draw[overlay,very thin] (0,-0.35) -- (0.05,-0.35); end{tikzpicture}~this is some text.



This is some text and ~this is some text.





end{document}

The code of the two last lines produce more or less what I am envisioning:

Any help here from the tikz masters?

One possible way.

This is some text and tikzmarknode{a}{~this} is some text.



This is some text and tikzmarknode{b}{~this} is some text.

begin{tikzpicture}[overlay,remember picture]  draw[very thin] 

([xshift=0.2em]a.west) -- ([xshift=-0.3pt]a.west)

([xshift=0.2em]b.west) -- ([xshift=-0.3pt]b.west);

 draw[semithick] (a.west) -- (b.west); end{tikzpicture}



This is some text and begin{tikzpicture}draw[overlay,thin] (0.05,0.1) -- (0,0.1); draw[overlay,semithick] (0,0.1) -- (0,-0.35); draw[overlay,thin] (0,-0.35) -- (0.05,-0.35); end{tikzpicture}~this is some text.



This is some text and ~this is some text.

ADDENDUM: For more general settings, you may want to work with styles and fill.
