# Why is there a blinking cursor on a \psdots? What is it for?

The red dot is made by \psdots while the blue one is made by \pscircle. By clicking the red dot viewed by Adobe Acrobat, there will be a blinking cursor. But a blinking cursor does not exist on the blue dot.

\documentclass[pstricks,border=12pt]{standalone}

\begin{document}
\begin{pspicture}[showgrid](3,3)
\psdots[linecolor=red](1,1)
\pscircle*[linecolor=blue](2,2){2pt}
\end{pspicture}
\end{document}


Why is there a blinking cursor on a dot produced by \psdots? What is it for?

\psdots uses characters from a self defined Type-3 vector font, also known as a softfont:

voss@shania:~/Test> pdffonts test.pdf
name                          type              encoding         emb sub uni object ID
----------------------------- ----------------- ---------------- --- --- --- ---------
Helvetica                     Type 1            Standard         no  no  no       8  0
[none]                        Type 3            Custom           yes no  no      11  0


With \pscircle you get a graphical object. For a character like the dot the cursor behaves as usual for other characters. And, by the way, it is an example that a Type 3 font can also be a vector font!
