Mac terminal shift+ direction key garbled

recently, I suddenly found a problem with terminal that comes with mac, including iterm2 and other command lines of app (such as vscode):
strange characters will appear when using shift+ direction keys (in fact, control+ direction keys will also have)

I don"t know how to solve it, so it"s the same with zsh instead.

in terms of what I have done recently, I have added several themes to terminal and upgraded the system
macOS version: 10.14.3

The

console only accepts input characters and is not responsible for understanding the meaning of the input behavior. So the mac console can not understand the meaning of your shift+ key operation, so it is directly escaped to input characters into the console.

You will be prompted-bash:-bash: command not found every time you open the terminal.
I have searched many methods in other ways, but I still can t find the answer. I hope I can find the answer to the question. Thank you . ...
