In the Manual, "OVR" sometimes is defined as "Overstrike" (Editing Items), and sometimes as "Overwrite" (9. Status Bar), which makes the search difficult.

 

Also, I suggest, in the Status bar page, adding a small description of what "Overwrite" does, or a link to the "Editing items" page, where this description can be found, because, usually, the user goes to the "Status bar" page in order to find what the "OVR" in the bottom of the page does, and the "Status bar" page, the way it is now, doesn't clarify much, nor point to the page where this clarification can be found.
