Okay, but what am I supposed to open in regard to editing keyboard shortcuts?
In the link that you guys linked it says:
"rc.xml
Tip: Custom keyboard shortcuts (keybindings) must be added to the section of
this file, and underneath the heading.
~/.config/openbox/rc.xml is the main configuration file, responsible for
determining the behaviour and settings of the overall session, including:
Keyboard shortcuts (e.g. starting applications; controlling the volume)
Theming
Desktop and Virtual desktop settings, and
Application Window settings
This file is also pre-configured, meaning that it will only be necessary to
amend existing content in order to customise behaviour to suit personal
preference."
So I tried to enter all kinds of different commands in the terminal but I
either get "No such file in the directory" or "command not found" or
"permission denied".
