Hi James,
The keyboard shortcut info is actually part of the wallpaper, so you can change the wallpaper.
with Microwatt many of the tweaks are a simple manual affair contained in one text file. (there is no gui or program to change the wallpaper) but its simple and fun to learn.
For the wallpaper using the file manager (pcmanfm) open your home directory (opens by default) and either hit Ctrl+H or click on "view - show hidden " in the menu and then open the folder named .i3
in there is a text file called "config" its a plain text file that will automatically open in a text editor when double clicking it.
you will find an entry under the heading of #startup apps
This line "default"
exec --no-startup-id feh --bg-scale /usr/share/wattOS/R9wall2.jpg
That is the path to the picture that is the wallpaper. You can change this to whatever path you like. For example if you have a picture in your home directory or elsewhere, you simply change that path and save and logout/login or restart and new wallpaper.
New line (picture I want)
exec --no-startup-id feh --bg-scale /home/biff/Pictures/mypic.jpg
