Symbols generated when Caps Lock is in action

Question

I am trying to figure out how keyboard layouts are defined (for Xorg). I more or less understand the formats of the /usr/share/X11/xkb/symbols/* files but the comportment of the Caps Lock key remain a mystery. How the symbols generated when the Caps Lock key is in action are configured? For example the French keyboard layout has a key that generate é (eacute) and the digit 2 when shift is pressed. When Caps Lock is in action it generates É (Eacute). If i change the eacute by à (aacute) in /usr/share/X11/xkb/symbols/fr then it generates À when Caps lock is pressed. This is logical but how Xorg know that À is the uppercase version of à?

Hi Abk,
Please try like this. It works for me.
declare
  key_pressed  VARCHAR(30) := 'FALSE';
begin
  key_pressed := :System.Mouse_Button_Shift_State;
           or
  key_pressed := :system.mouse_button_modifiers;
  if upper(key_pressed) = 'CAPS LOCK+' then
     <your logic>
  end if;
end;Also, are you meeting the condition i wrote above of pressing caps lock along with left mouse click?
If this doesn't work, try debugging your code. Stop in the when-mouse-click trigger and check if it is going inside the if condition.
Check what is the value of key_pressed.
Hope it helps.
