Ctrl and PF keys with emacs or Sublime Text - Alain Maronani - 05-28-2018
I am running 2 separate system. One with ubuntu 18.04 lts using emacs 25.3 (and 24.3) and sublime text (registered copy) 3175. The other one Linux lite (most current release) I can use a combination of keys such as;
For emacs Ctrl-f12 is mapped to ido-switch-buffer-other-frame (opening a buffer on a separate emacs frame).
For emacs Alt-f12 is mapped to ido-switch-buffer-in-another-window (opening a buffer on a separate emacs window)
For sublime text Ctrl-f4 is mapped to to the function close windows (standard key mapping for sublime-text).
With linux lite nothing works. Ctrl-f12 is not linked to a global keyboard mapping (i did a check using dconf) and xev shows the good keys. Ctrl-f4 for sublime-text is not linked to a global keyboard mapping
emacs version are the same, sublime-text version are the same. plugins and emacs packages are the same, configuration are identical.
I a word combination of ctrl key (or Alt) and a function key not mapped globally are not transmitted to the running application (in scope). ctrl-f4 in sublime-text does nothing and emacs mapping such as Ctrl-f12 also. I have other emacs function (browsing emacs buffers) using Ctrl-f7 and Ctrl-f8 and they too are not working also (no response form keyboard pressing).
Linux lite is using gtk-2 and ubuntu gtk-3. Any idea somebody ?

I am documenting the solution. First look here (a long discussion on xfwm4, xubuntu, xfce).
https://bugpad.net/ubuntu/+source/xfwm4/+bug/1292290s.launch
Keyboard standard action or combos (pfkey, alt..) are directed with the file .config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml
Mine is here (before editing).

File is created from standard template located at /etc/xdg/xfce4/xfconf/xfce-perchannel-xml when you define a new user.
By default keys combo such as default (Control key) + pf12 or Alt key + pf12 are already assigned to xfwm4 or something else (please look at custom action also). Not ALL Key combos are displayed by xfce4-keyboard-settings (from menu or from the shell). The only way to change custom action is by editing (xml file) your file located at .config/xfce4/xfconf/xfce-perchannel-xml/xfce4-keyboard-shortcuts.xml. You can also edit the standard template located at /etc/xdg/xfce4/xfconf/xfce-perchannel-xml (not recommanded...) as a standard before creating new users or before resetting your keyboard configuration using xfce4-keyboard-settings.
If you reset your keyboard settings using xfce4-keyboard-settings it also reset ALL custom action to the default. I have difficulty to understand the usefulness of having ctrl key + pf12 mapped to a switch to the twelve workspace...by default. It should be not assigned or at least should be documented. Same as using Alt+Insert (adding workspace) or Alt+Delete (deleting workspace)
In a word if you are experiencing difficulty with mapping for some applications look here FIRST.
