Is it possible to change the name displayed on F1 key to something else (SUS for example)?
Sure, it is.
Edit file /usr/share/florence/styles/default/symbols.xml.
Look for something like :
and just change the label to whatever you want.
You can customize any key you want just like that.
How about changing symbols of special keys, Super key for example? The syntax is not so simple for me to understand.
The symbol element takes either a <label> or a <svg> element.
If you just want to use a label, then you can change the Super key to look like this:
Note this will change both super keys (right and left).
You could change them independently like this:
Now if you want to use a drawing instead of a label, you need to use a svg element, like the one used in the original symbol.xml file:

And indeed, the svg syntax is not simple. The full documentation for svg can be found here: http://www.w3.org/TR/SVG11/
But don't worry, there is no need to read this. You can just install inkscape: http://inkscape.org/ (or install it from your distro repository). Inkscape is a WYSIWYG editor to create svg files. Edit your symbol with inkscape and save it as simple svg. Then you can view your svg file with a text editor and copy it in the symbol element of the symbol.xml file.
In inkscape, you can select the class of the drawing elements. Elements that have the "symbol" class will use the color selected in the configuration dialog of Florence. That is because Florence uses a css that is generated from the /usr/share/florence/florence.css template. This template file looks like this:
As you can see, the elements that have the symbol class are filled with the symbol color and outlined with the symbol outline color (2 pixels wide).
I understand the process is not so simple, as it requires some knowledge and is not documented enough. A style editor is planned for the future and that should make it a lot easier to customize the symbols. The problem is that there are a lot of features that have a higher priority and I have little time to do it. I'm afraid it won't be implemented before 2013 or so. Please understand I'm alone on this project as of now and I am not very good at recruiting new volonteers so bear with me.
Anyway, I hope this helps a bit.
