Okular: how to remap builtin j,k,h,l navigation keys to something else


I am using non latin1 keyboard layout and the keys j,k,h,l maps to different keys in my keyboard. I really like vim like navigation and I appreciate okular provides this. However these keyboard shortcuts can not be configured in configure keyboard shortcuts dialog under okular settings. I have not been able to find a solution for this.
I appreciate any insight, help.
