Nice one, i like your next update by now 🙂

>-Add a function to set the key of a button to NULL, >because some games need STRG+ALT left mouse or other
You can set key to STRG and check on alt, this does not work?
– Ah…. yes it works

>-Add a function to a button by holding them
Please can you explain that a bit more?
-Ok i press the button and it hold the key that i want and release the key if i press it one more. That is nice to switch right mousebutton hold on/off or strg + g, whatever
