TextField help required!

[jackofall]

hi,
I have to develop a form which will contain some textFields and i need this functionality in it.
Actually, it will take input for some goods etc.
There will be some textfields and i saw there are related things like autotextEditField and other classes and interfaces but just want to ask if anyone did this before, can guide me through.
When user press 1 or Math focus of input will go to the first textfield editing area and when user press 4 or eng control or (focus) will go to the 4th textfield and user enter its value.
e.g
1. math-marks ____
2. phy-marks ____
3. bio_marks ____
4. eng_marks ____
Any idea how can i develop this functionality?
Thanks & Regards
