The most likely solution would be to use a 'hook' - these are a feature of the OS that allows you to gain control before, during or after certain OS operations, such as keypresses or calculations. There is some general information here (for the 83+ but it's the same concept): https://wikiti.brandonw.net/index.php?title=83Plus:OS:Hooks
The issue on the CE is that apps are not allowed, so you need to be careful/creative as a hook is expected to be in the same location at all times. If something overwrites RAM or a garbage collect occurs then it may be marked invalid or even crash.
