[Dirtfuyan]

i'm prepare DIY machine.
The touch area needs to be mapped.
Found that the keyboard cannot be pressed long.
I'm a rookie in C language.
How to modify it？

You probably need to learn basic things about Windows API before you dive in and you may want to check controller callback which defined in here:

Additionally, check KeyboardController.cpp, it might not interpret windows message correctly for hold input.
Note that I'm no longer actively maintain this, but I'll happy to merge your PR if you decide to make a fix.
