EDIT via rotary encoder

[cemik1]

Based on your examples I prepared MENU controlled by rotary encoder. It works well (FIELDs timeOn and timeOff are fully controlled) except EDIT field. Trying edit buf1 string value by encoder only down change is possible. Encoder counter is displayed and both move directions are properly detected (up and down). It is also possible edit this string by serial input so menu system seems be correct. Could you advice is it my fault or some library issue?
I have also tested it with SSD1306 display and other encoder/button library with the same result.
Platform ESP32, project enclosed

/********************
Generic Rotary/Button input
output: serial
input: serial, clickable rotary encoder

purpose:

  Having a generic rotary event-based implementation,
  leaving rotary and button libraries up to the user.
  Example uses QDEC and AceButton, but could be anything
  that suits your particular hardware and/or needs.

  TODO: userland rotary/button event mapping to menu actions,
  as doubleclick/longpress are now hardcoded to back.

I think I found problem source. There is encoder CW move event definition in rotaryEventIn.h file:
ROTARY_CW = 1 << 4,
It means 0x08 is code for this event,
But during text field processing (items.cpp file) this value is decoded as backspace event first:

void textField::parseInput(navNode& nav,menuIn& in) {
  trace(MENU_DEBUG_OUT<<"navTarget::parseInput"<<endl);
  if (/*charEdit&&*/in.available()) {
    char c=in.peek();
    if (options->useNavChars&&(c==options->getCmdChar(upCmd)
      ||c==options->getCmdChar(downCmd)
      ||c==options->getCmdChar(enterCmd)
      ||c==options->getCmdChar(escCmd))) {
        navTarget::parseInput(nav,in);
        return;
      }
    switch(c) {//special cases
      case 0x0D://enter
        in.read();
        charEdit=false;
        dirty=true;
        // edited=false;
        cursor=0;
        nav.root->exit();
        return;
      case 0x08://backspace
        in.read();
        buffer()[cursor]=validator(cursor)[0];
        if (cursor) cursor--;
        dirty=true;
        return;

I am only amateur c++ coder so my solution is to change CW definition in rotaryEventIn.h to:
ROTARY_CW = 1 << 5
Now project works as expected and text field can be edited by rotary encoder.

Please update library in proper and elegant way.
