I think originally it was use to make complex insets behave like single
characters for cursor movement. I.e. you could 'lock' a, say, fraction
containing \frac{\partial}{\partial x} and it would act as a single unit
afterwards, i.e. the cursor would move from before the inset to behind
the inset with a single 'CursorRight' stroke, and not enter the
numerator of the fraction.
Having said that, I have no idea how 'locked' is used nowadays.

Hard to believe anyone reads documentation ;-)
