"Step Into My Code" from the debugger panel is missing in the settings panel, only "Force Step Into" appears

I was about to switch the shortcut keys between "Step Into" and "Step Into My Code".

However I could not find "Step Into My Code" in the settings panel.

Seems like both "Step Into My Code" and "Force Step Into" share a common Shortcut Key, However it was confusing to find, and honestly I am still not sure if I can or cannot set different shortcut keys between those two.
