# How can Fingerterm map Shift+Backspace to Delete?

After making a backup copy of the file named finnish.layout, I changed the backspace line to [":backspace", 0x1000003, ":delete", 0x1000007]. After closing and re-opening Fingerterm, though, with the Shift key active, the backspace symbol does not change to a delete symbol, and the key action does not change to delete-character-ahead from delete-character-behind. How can I fix this? Is it unfixable?
