Is it possible to make a shortcut for backspace in Ubuntu?

Question

ubuntu

In order not to stretch the little finger to press backspace, I would like to make a shortcut, for example. Shift+J to remove typos.

Answer 1

You can do it with the help of the library https://github.com/alols/xcape
right Alt as a backspace:
xcape -e 'Alt_R=BackSpace'
delete the entire word by pressing the right Ctrl:
xcape -e 'Control_R=Control_L|BackSpace'
