Kenrick Mock has just announced on his blog (http://www.math.uaa.alaska.edu/~afkjm/techteach/?q=node/86) that the new versions of PenAttention and CursorAttention (v1.4) are now available from http://www.math.uaa.alaska.edu/~afkjm/PenAttention/
He has also provided some videos to show how to use the latest new features.
Quoting from Kenrick’s blog post:
There are two new features:
1) Hotkey to turn the highlight on or off. You can use either CTRL-F9 or CTRL-ALT-F9. This can be handy on a Tablet PC if you map the hotkey to one of the hardware buttons.
2) Option to use a custom image in place of the default pencil. Create your image file as a PNG and name it CustomPen.png and put it in the program installation folder. Restart PenAttention and it will use the new image if you select the pencil tool.
See https://explainingmaths.wordpress.com/2010/11/29/high-visibility-pointers-for-teaching-and-screencasts/ for the way I use the new features.
I found that there was a slight clash with <ctrl><f9> and PDF Annotator: that key combination always puts PDF Annotator back into pen writing mode. I will see whether <ctrl><alt><f9> avoids this.
