I am interested in creating a symbol-sized tikz drawing with a rectangle half the width of the symbol (and the height of a symbol) and an arrow coming out from the middle right side of the rectangle pointing to the right (the arrow head should be rather small). I tried to do something like that here (the A symbol is for comparison in size), but it didn't quite work right:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning}
\begin{document}
\begin{tikzpicture}[
node distance = 0mm,
box/.style = {% definition of rectangle as node
draw, line width=0.35mm,
text width=11pt, minimum height=11pt, align=left,
inner sep=1mm, outer sep=0pt}
]
\node (box1) [label=above:{}] {};
\node (B) [draw, right=of box1] {};
\draw [->] (box1) -- (B);
\end{tikzpicture}
A
\end{document}
How do I make the width of the square half its size?
How do I make the arrow leave the right side of the rectangle?
How do I make an "empty" node to the right of the rectangle so I can draw an arrow to it?
How do I make the arrow head smaller?
