accelerators not working

Issue
I was trying to change the keyboard shortcuts via gtk accelerators overriding. There is no error, but the default accelerators are still in use.

Steps to reproduce
Example to change ctrl+g -> F3
sed -ir 's/(^.*SearchFindNext\" \").*$/\1F3\"\)/' ~/.config/xed/accels

Expected behaviour
Accelerator will override the default values in code.

Other information
Provide a way, how to change default keyboard shortcuts without code changing.
