Create custom shortcuts on tryton

To me, it seems that the method mentioned above does not longer work. A working, but limited method - editing accel.map - is described here.

Unluckily, it only seems to apply to the “form” section. Now I’d like to change

  • present “ctrl-k” to “ctrl-l” and
  • present “ctrl-tab” to “ctrl-pgdn”
  • present “ctrl-shift-tab” to “ctrl-pgup”

to make tryton behave more like browsers when dealing with tabs and the top text box. Is there a method to do that without coding?

Cheers,
Wolf
