What you probably should do is save the state, the user is currently in using his unique id.

I don't have experience using nodejs for telegram bots, so the following code is kind of pseudo.

userStateMap = {};

switch ($chat.text)
{
    case "/start":
          sendWelcomeMessage($chat);
          userStateMap[$chat.id] = 0; // save the state
          break;
    case "1":
          $chat.text = "you clicked 1";
          $chat.reply_markup = getCustomKeyboard();
          return sendMessage($chat);
          userStateMap[$chat.id] = 1; // save the state
          break;
    case "about":
          $chat.text = "you clicked about";
          $chat.reply_markup = getCustomKeyboard();
          return sendMessage($chat);
          userStateMap[$chat.id] = 4; // save the state
          break;
    case "2":
          $chat.text = "you clicked 2";
          $chat.reply_markup = getCustomKeyboard2();
          return sendMessage($chat);
          userStateMap[$chat.id] = 2; // save the state
          break;
    case "previous":
          $chat.text = "you clicked previous";
          $chat.reply_markup = getCustomKeyboard(userStateMap[$chat.id]); // use the saved state
          return sendMessage($chat);
          break;
    case "3":
          $chat.text = "you clicked 3";
          $chat.reply_markup = getCustomKeyboard3();
          return sendMessage($chat);
          userStateMap[$chat.id] = 3; // save the state
          break;
}

//customize getCustomKeyboard to receive the state and use it to calculate the next keyboard

So you would update the state after each request, and for requests like previous you would calculate the needed keyboard depending on the last saved state.

What RegExp? Do you still need help with this one? Just update your question with the newest code and problem. — Loki, Jan 31 '17 at 09:10

Solved With callback_query and Inline Keyboards

const helpKeyboard = [[{
    text: `back`,
    callback_data: `back3`
}]]



bot.on('callback_query', msg => {
 if (msg.data == `back3`) {
}
}
