Letter "e" not working in Linux terminal?

Question

MySQL

Hello.

For some reason, the small "e" in the terminal stopped working for me. In this case, a large "E" is displayed without problems. Because of this problem, many commands in the terminal do not work, because e is ignored even when copying a command with the letter e

Answer 1

SELECT DISTINCT order_id FROM TableName WHERE item_id = 101 OR item_id = 102

SELECT DISTINCT TableName_101.order_id
  FROM TableName AS TableName_101 
    INNER JOIN TableName AS TableName_102 ON TableName_101.order_id = TableName_102.order_id
  WHERE (TableName_102.item_id = 102) AND (TableName_101.item_id = 101)

Answer 2

The letter "e" stopped working for me after adding the following values ​​to ~/.inputrc:
"\e[A": history-search-backward
"\e[B": history-search-forward
As I commented out these lines, it started right away. (these lines make it convenient to search through the history of entered commands) conditionally, you write nano and press the up arrow and you will be listed with the commands that you entered earlier. I’m doing something wrong, if my letter e falls off. Debian 10 system
