macOS: Right Arrow / Ctrl-F don’t accept inline (ghost-text) suggestions in Codex CLI

What version of Codex is running?

CLI Version: 0.41.0

Which model were you using?

gpt-5-codex

What platform is your computer?

Darwin 24.6.0 arm64 arm

What steps can reproduce the bug?

Summary
On macOS, Codex CLI shows grey inline (ghost-text) suggestions, but pressing Right Arrow does not accept the suggestion. Using Ctrl-F also fails to accept suggestions. The terminals are sending the expected sequences (verified with cat -v), so the keypress is reaching the TTY, but Codex doesn’t treat it as “accept”.

Steps to reproduce

1. Launch Codex in a git repo: codex
2. Start typing a prompt until a grey inline suggestion appears (e.g., “Improve documentation in @filename”).
3. Press Right Arrow (→).

What is the expected behavior?

The ghost-text suggestion is accepted into the input line.

What do you see instead?

Nothing happens; the suggestion remains ghost text and the cursor simply moves (or no visible effect).

Additional information

Diagnostics / what I tried
• Verified terminals send the correct sequences:
• cat -v then press Right Arrow → prints:
^[[C

(i.e., ESC [ C)

macOS Terminal - doesn't work

iTerm2:
• Profile “Codex” → Keys → Key Bindings:
• Right Arrow → Send Escape Sequence → [C
• Also tried mapping Option+Right → [C
