Key Codes

[timprograms]

I want to be able to use my android to develop and use a basic bash...
What I need is a program that will take the key code
and change them to modified codes then convert it to chars
then give it to a program it so that I can have all my characters
heres my idea so far...
use ansi codes to change it...
i dont know the syntax (so if someone would give an example that'd be good)
its basically
\033[String;Code;p
i dont know what is string and what is code??
also how would i give the a program my modified keys???
