How to set ctrl+c to copy, ctrl+v to paste and ctrl+shift+c to kill process in xfce4-terminal?

Accepted answer doesn't work anymore (e.g. xfce4-terminal 0.8.7.4 on lubuntu 18.04.2) because of the GTK3 change, as said HERE. It would seem that the only way to change the keyboard shortcuts is by modifying the config file:

~/.config/xfce4/terminal/accels.scm

Open the file, search for 'copy' and replace ; (gtk_accel_path "<Actions>/terminal-window/copy" "<Primary><Shift>c") with (gtk_accel_path "<Actions>/terminal-window/copy" "<Primary>c")

That is: change the shortcut, but also remove the ; before the line.

The same for "paste", replace: ; (gtk_accel_path "<Actions>/terminal-window/paste" "<Primary><Shift>v") with (gtk_accel_path "<Actions>/terminal-window/paste" "<Primary>v")

Restart terminal.

In xfce terminal go to Edit, hover your mouse over Copyand press ctrl+c.

Same goes for paste.

Kill process gets automatically reassigned to ctrl+c+shift.
