Newcomer needs help

I have edit fields intended for user input of numbers only; one decimal point 
only anywhere in the field; one minus sign if needed only as first character 
and no other characters permitted. My code for this works fine.

However, I would like to give user the ability to delete a wrong number if 

I have been unable to enable the delete key if I use the filter I have coded.

Would really appreciate any suggestions.
