The dot key no longer leads to the item selected

what button have i accidentally clicked!
used to be if i select and object then clicking the dot key (bottom right on the keypad) blender would zoom into to it.
does not do that on this file.
thanks all

It works on other files, just this one does not?
Try change the workspace and/or edit/object mode and try again.

Yes “It works on other files, just this one does not?”
how do i “Try change the workspace and/or edit/object mode and try again.”
thanks

Changing workspace: On the top border you have “Layout”, “Modelling”, “Sculpting”, …
Change actual workspace from “Layout” to “Modelling” and check if dot key works.
Do this with change between edit / object mode via tab key too.

thanks
2.69 must have put them somewhere else!

I opened a new file and put all the items in there.
so that solved it
