NetBeans user Sarel van der Merwe from Total Index in South Africa wants me to add new features to the NetBeans Cheat Sheet plugin. I found I'd lost the sources so recreated the plugin today, it looks as follows, i.e., it embeds a window to the right of the editor where your keyboard shortcuts and Java code templates are listed as a handy reference:
I've provided an updated plugin hopefully with more or less the same functionality to everyone's liking:
http://plugins.netbeans.org/plugin/49660/netbeans-cheat-sheets
Install it into NetBeans IDE 8.0.1, probably won't install in earlier releases. I've found it to be a pretty handy tool.
For further enhancements, the source code is now publicly available here:
