You're getting undefined because the position you're checking for in the array arr doesn't exist for lowercased letters since you're subtracting it from "A".charCodeAt(0). You can modify

This is the answer to my problem: I needed to scan the individual channels to determine which one was being pressed. Here is the code, in case anyone is interested:

Rather than addch for that special case, you can insert a character using insch:

These routines insert the character ch before the character under the cursor. All characters to the right of the cursor are moved one space to the right, with the possibility of the rightmost character on the line being lost. The insertion operation does not change the cursor position.

For instance, you could decide to use that when the current cell contains something other than a blank. You can read that character using inch (similar spelling, different meaning):

These routines return the character, of type chtype, at the current position in the named window. If any attributes are set for that position, their values are OR'ed into the value returned. Constants defined in can be used with the & (logical AND) operator to extract the character or attributes alone.

(as noted in the manual page, AND the return value with A_CHARTEXT to get just the character).

I think you can use a timer If user tap twice within 150ms then it is a double tap.

You can make a list of lists. No need to assign each list to a sequentially named variable.

The idea here is that a List is a collection of objects. An instance of a List is itself an object. Therefore a List object can contain other List objects.

We declare a list of lists: List < List < … > >

The keypad function applies only to the window given as its parameter. When you use newwin, etc., those return a window where the keypad mode is not set.

The newwin documentation points out

Regardless of the function used for creating a new window (e.g., newwin, subwin, derwin, newpad), rather than a duplicate (with dupwin), all of the window modes are initialized to the default values. These functions set window modes after a window is created:

Two things I see missing here.

One is final void Function()? onPress;. Since earlier the return type was not acurately specified.

Seccond is onTap: onPress. Since earlier your were just returning your function variable and not calling your onPress function. This can also be written as onTap: () => onPress?.call()

You can rely on signals to terminate both processes. Under the hood, the Process.terminate() method delivers a SIGTERM signal to the target process. You need a Queue or Pipe to sent to the processes each other PID. Only the parent (main) process can do so. In your main code before the two processes create a pipe.
