1) Look at http://ampere.scale.uiuc.edu/~m-lexa/cell/cell.html

2) copy into your HTML page the part that is a form ( <FORM>.......</FORM>

3) Make all the buttons TYPE="hidden"

4) Set NAME="keyword" (or something like that, it's the last one) to
VALUE="photosynthesis" (or something else; only photosynthesis and respiration
work right now, but if you tell me which other frames in the system you want
to jump to, I can set a keyword for them)

5) Add a visible TYPE="submit" button to this form, that the user will press.
This should get him to the right frame of my system
