I prefer backspace right above "enter". In windows this can be accomplished with autohotkey. On my desktop a HKKB keyboard has this layout built-in.
Following Custom keyboard layouts (Ubuntu) has me swapping
usr/share/X11/xkb/symbols/pc. This yields the behavior that both backspace and backslash enter a backslash, rather than swapping the keys functionality. Swapping via
xcape -e 'BackSpace=backslash' and its alternate will insert then delete a backspace.
How can backspace and backslash be swapped in Ubuntu?
