⌘← and ⌘→ hotkey navigation in Claude Code and Codex

You can make ⌘+Left and ⌘+Right hotkeys navigate Claude Code and Codex terminal input to start and end of lines. This post focuses on iTerm2 for macOS but this should work in virtually any terminal supporting keybindings.iTerm2 → Preferences → Profiles → Key Bindings Click + and set the hotkey to: ⌘+Left Use the action: “Send Hex Code” Use hex code: 0x01 For ⌘+Right: Same sequence as above but set ⌘→ to use hex code: 0x05 Command Up and Down ⌘↑ and ⌘↓ are a bit of a hack but will work in most cases on Codex. If you know what needs to be sent to CC, please comment: Map ⌘-Up arrow to 25 Up arrows plus Home, and vice-versa for ⌘-Down: Same as before; iTerm2 -> Preferences -> Profiles -> Key Bindings– Click + and set: Cmd+Up– Use the action: “Send Hex Code”– Hex Code: ⌘↑ 0x1B 0x5B 0x41 0x1B 0x5B 0x41 0x1B 0x5B 0x41 0x1B 0x5B 0x41 0x1B 0x5B 0x41 0x1B 0x5B 0x41 0x1B 0x5B 0x41 0x1B 0x5B 0x41 0x1B 0x5B 0x41 0x1B 0x5B 0x41 0x1B 0x5B 0x41 0x1B 0x5B 0x41 0x1B 0x5B 0x41 0x1B 0x5B 0x41 0x1B 0x5B…
