What issue are you seeing?

When I push CTRL + DELETE in the CODEX CLI it only deletes one letter instead of full words.

What steps can reproduce the bug?

1. Open Codex by running command "codex" in terminal
2. Write "hello world" in codex terminal (without hitting enter)
3. Move the text cursor/caret to the first part of the line; (i.e before the word hello)
4. Push CTRL + DELETE
5. Notice that only one letter is deleted at a time

What is the expected behavior?

Expected behavior is that it would delete the full word "hello" when clicking CTRL + DELETE one time and then "world" in the next.
