I found out how to get other layouts on Matchbox keyboard ... In /usr/share/Matchbox Keyboard, there are several files. Some are keyboard layouts and some are fragments. Take whichever one you want to use as layout and move it to /home/user/.matchbox, and name it "keyboard.xml". I'm using "keyboard-lq1", and it's all I need.... You can also edit it however you want ...(I have dpad arrows and ctrl/alt on mine).
