Ignore combined keys

[aSa]

Hello,
I use an external programmable keyboard (a keypad with QMK firmware) which allows me to get several layers with a few keys.

Is there a simple way to have all single keys intercepted by LuaMacros, and all the key combinations ignored?

For example, I program my keypad to send "F4" with the 1st key and "CTRL + F4" with the 2nd key.

I would like LuaMacros
to interpret only the "F4" alone to launch a software
and ignore the “CTRL- F4” which should be transmitted as is to the system

If I set a trigger for the whole keyboard, all the keys are blocked by LuaMacro and I am therefore obliged to code again all the key combinations to get them repeated.

I managed to know the CTRL key status with a variable that I set depending on whether the key is pressed or released

Code: Select all

lmc_set_handler('KeypadQMK',function(button, direction)

    if (button == 17 and direction == 1) then -- CTRL DOWN
        QctrlFlag = true
    end
    if (button == 17 and direction == 0) then -- CTRL UP
        QctrlFlag = false
    end

        if (direction == 1) then return end  -- ignore down

        if (button == 115 and QctrlFlag == false) then 
            -- F4 detected
            lmc_spawn("calc")
            
        elseif (button == 115 and QctrlFlag == true) then 
            -- CTRL + F4 detected
            lmc_send_keys('^{F4}')

        else
            print('not  yet assigned: ' .. button)
        end
end) 

It works but since I have a lot of keys which are CTRL, SHIFT, ALT, or Window key combinations, I would like to avoid having to redefine them one by one.

Something like this would be perfect :

Code: Select all

    if (direction == 1) then return end  -- ignore down
    if (QctrlFlag == true or QaltFlag == true or QshiftFlag == true or QwinFlag == true) then 
        -- leave it as is and pass it to the computer
     else 
            if (button == 115) then  lmc_spawn("aaa")
            if (button == 116) then  lmc_spawn("bbb")
            if (button == 117) then  lmc_spawn("ccc")
    end

Thank you for any help et please, excuse my bad english

This can't be done. The callback can be attached to whole keyboard or to single key. But modifiers (alt, ctrl) do not play a role as they are considered as key themselves. And also luamacros main idea is to have multiple keyboards so you can do actions with single key - to avoid using complex modifiers (ctrl+alt+something)

Unfortunately, that's what I understood : I have to explicitly code each key combination.

Thank you for your answer and for this software

If someone has a similar need to mine, i.e. just a numeric keypad with several layers to send key combinations, open predefined folders or launch programs;
I finally found Clavier+

This software is small, portable, easy to configure, and - with a 2 days experience - perfectly running.

Unlike LuaMacros, it is not able to recognize different keyboards, so you have to use a programmable numpad with key combinations that are never used (Example CTRL + ALT + WIN + F1) to avoid confusion with the main keyboard
