when editing kma file headers in version 2.212, when it comes time to highlight the selection you are editing, and delete it to replace it the way you want it, the space bar (which is easier to reach, than the delete key) will delete the selection.
HOWEVER, do not do this! It will insert an unseen space at the start of the field that will throw off the alphabetical sequence you are trying to achieve.
Fortunately... I discovered this before I spent to many hours doing it this way.
