Notes:

All operations take place in read-only mode.

Only if you exit the edit mode and there are changes and you explicitly confirm this will the file be temporarily opened for read/write.

With inserted or deleted bytes, the write can be huge, so it happens always in place.

The last address is auto set with initial Find, Goto w/o relative, home/end or manual with l.
