I have uploaded it to my site at

Note that while I use it to remind me of the shell command-line interface key shortcuts, you can easily adapt it for anything you want. When you unzip it you have an application folder which you can place anywhere; I keep it in my ~/my-roxapps folder but you might want to keep it in /usr/local/apps
Of course you need to drop the application folder onto the desktop to see it there.
Incidentally, it is best to put the icon at the bottom screen to give it maximum room.
To alter the files in the application shift-click it, or right-click it and choose "Look Inside" from the popup menu. There are only 3 files in there:
AppInfo.xml - is the most important because it is a text file that gives the popup text.
AppRun - is a shell script. I normally have this pointing at a document on the bash shell in a gigantic reference folder on my machine, but I've altered it for you so it simply opens the AppInfo.xml file in the default text editor.
.DirIcon - is the application's icon. You can replace this with any that is more to your taste.
Hope this is of use to someone.
