From the first Google result when searching for "wpf gotfocus vs gotkeyboardfocus[^]":

c# - The difference between GotFocus and GotKeyboardFocus - Stack Overflow[^]

WPF has 2 concepts regarding focus. There is the physical keyboard focus, and there is logical focus.

Only one element can have keyboard focus (and if the application isn't the active application, no element will have keyboard focus).

Multiple items can have logical focus.
