I've just installed xubuntu 17.10 and cannot change xfce4-terminal keyboard shortcuts. I tried enabling editable accelerators (according to http://docs.xfce.org/faq), running:
Appearance -> Settings -> Menus and Buttons -> Enable editable accelerators: Tick
but when I hover the mouse over any menu item and press any key combination, nothing happens; I can see all shortcuts are greyed out, indicating that they can't be changed. I closed/reopened xfce4-terminal, and also logged out/in from the xfce session, to no avail, still can't change the shortcuts.
Don't know what changed in xfce because I remember being able to do this in past versions. I'm running fresh xubuntu 17.10, so xfce is version 4.12.3 and xfce4-terminal is 0.8.6-0ubuntu1.
Would anybody know how to change them ?
EDIT: I've just discovered that they can be changed editing:
~/.config/xfce4/terminal/accels.scm
Remove the leading ; from the menu entry and edit the shortcut. xfce4-terminal has to be closed/reopened for the new shortcuts to take effect. Not sure if this is the standard way of doing it, but at least it works.
EDIT 2: Found a good explanation about it here
~/.config/xfce4/terminal/accels.scm
file doesn't seem to have any effect for me (xfce4-terminal 0.8.3 on MXLinux 17)
