shortcut key function in CLI doesn't working

hello,
I found that the shortcut key such like `alt+b` and `alt+f` (it change to search) doesn't working in shell command line.

I press keyboard frequently within **move cursor back a word**(alt+b) and **forward cursor to word**(alt+f) but failed.

would you please add a custom key map function in feature release?

familiar issue like #1135

Start by reviewing related issue #1135 and the CLI shell command-line input behavior described here. Determine the existing shortcut handling and define how a custom key map should cover Alt+B and Alt+F; done means those shortcuts work for moving by words and can be customized.
