Arithmetic on tikzmark points
Can I do arithmetic on tikzmark points? For example if I have tikzmark{A} and tikzmark{B} can I find their midpoint?

Thanks Marmot! The tikzmark part of your example works fine, but the tikzmarknode is an "undefined control sequence" for me, even after reinstalling MacTex/Tex Live. I guess it's in some version of the tikz packege that has not yet been added to the main distribution?

Welcome to TeX.SE! You can use calc for that. In general, the midpoint between a and b is given by ($(a)!0.5!(b)$). One slight subtlety is that you have to prepend pic cs: to the tikzmark coordinates, but not for tikzmarknode nodes. The following MWE illustrates this.
documentclass{article}
usepackage{tikz}
usetikzlibrary{tikzmark,calc}
begin{document}
Hellotikzmark{A} something elsetikzmark{B}.begin{tikzpicture}[overlay,remember picture]
draw[red,latex-] ($(pic cs:A)!0.5!(pic cs:B)$) -- ++(0,-1);
end{tikzpicture} tikzmarknode{H}{Hello} world and tikzmarknode{M}{marmots}!begin{tikzpicture}[overlay,remember picture]
draw[red,latex-] ($(H)!0.5!(M)$) -- ++(0,-1);
end{tikzpicture}
end{document}
