## Why Picker-style UI in the TUI has accumulated a mix of hardcoded navigation keys. Some lists supported page movement, some did not; some accepted Vim-like keys, while others only accepted arrows; and tabbed or horizontally adjustable pickers had no shared keymap action for left/right movement. This PR makes picker/list navigation consistent and configurable so users can rely on the same defaults across the TUI. ## What Changed - Adds shared list keymap actions for: - vertical movement: `move_up`, `move_down` - horizontal movement: `move_left`, `move_right` - paging and jumps: `page_up`, `page_down`, `jump_top`, `jump_bottom` - Adds defaults: - Up/down: arrows, `Ctrl+P/N`, `Ctrl+K/J`, and plain `k/j` where text input is not active - Page up/down: `PageUp/PageDown` and `Ctrl+B/F` - First/last: `Home/End` - Left/right: `Left/Right` and `Ctrl+H/L` - Wires the shared list keymap through picker and list surfaces including session resume, multi-select, tabbed selection lists, settings-style lists, app-link selection, MCP elicitation, request-user-input, and the OSS selection wizard. - Keeps search behavior intact by reserving printable characters for query text in searchable pickers. - Updates keymap setup actions, config schema, snapshots, and focused coverage for the new list actions. ## How to Test 1. Start Codex from this branch and open the session picker, for example with an existing session history. 2. In the session list, verify that `Ctrl+J/K` moves the selection down/up. 3. Verify that `Ctrl+F/B` pages down/up and `Home/End` jumps to the first/last visible session. 4. Type printable search text such as `j` or `k` and confirm it updates the query instead of navigating. 5. Focus a picker control that changes values horizontally, such as a session picker toolbar control, and verify `Ctrl+H/L` changes the focused value like left/right arrows. Targeted tests run: - `cargo test -p codex-tui keymap::tests::` - `cargo test -p codex-tui keymap_setup::tests::` - `cargo test -p codex-tui horizontal_list_keys` - `cargo test -p codex-tui page_and_jump_navigation_use_list_keymap` - `cargo test -p codex-tui ctrl_h_l_move_provider_selection` - `cargo test -p codex-tui scroll_state::tests` - `cargo test -p codex-tui switching_tabs_changes_visible_items_and_clears_search` - `cargo test -p codex-tui toggle_sort_key_reloads_with_new_sort` Also ran `just write-config-schema`, `just fmt`, `just fix -p codex-tui`, `just argument-comment-lint`, and `git diff --check`. Note: `cargo test -p codex-tui` was attempted and still aborts in the pre-existing `tests::fork_last_filters_latest_session_by_cwd_unless_show_all` stack overflow, which is unrelated to this branch.
codex-core
This crate implements the business logic for Codex. It is designed to be used by the various Codex UIs written in Rust.
Dependencies
Note that codex-core makes some assumptions about certain helper utilities being available in the environment. Currently, this support matrix is:
macOS
Expects /usr/bin/sandbox-exec to be present.
When using the workspace-write sandbox policy, the Seatbelt profile allows
writes under the configured writable roots while keeping .git (directory or
pointer file), the resolved gitdir: target, and .codex read-only.
Network access and filesystem read/write roots are controlled by
SandboxPolicy. Seatbelt consumes the resolved policy and enforces it.
Seatbelt also keeps the legacy default preferences read access
(user-preference-read) needed for cfprefs-backed macOS behavior.
Linux
Expects the binary containing codex-core to run the equivalent of codex sandbox linux (legacy alias: codex debug landlock) when arg0 is codex-linux-sandbox. See the codex-arg0 crate for details.
Legacy SandboxPolicy / sandbox_mode configs are still supported on Linux.
They can continue to use the legacy Landlock path when the split filesystem
policy is sandbox-equivalent to the legacy model after cwd resolution.
Split filesystem policies that need direct FileSystemSandboxPolicy
enforcement, such as read-only or denied carveouts under a broader writable
root, automatically route through bubblewrap. The legacy Landlock path is used
only when the split filesystem policy round-trips through the legacy
SandboxPolicy model without changing semantics. That includes overlapping
cases like /repo = write, /repo/a = none, /repo/a/b = write, where the
more specific writable child must reopen under a denied parent.
The Linux sandbox helper prefers the first bwrap found on PATH outside the
current working directory whenever it is available. If bwrap is present but
too old to support --argv0, the helper keeps using system bubblewrap and
switches to a no---argv0 compatibility path for the inner re-exec. If
bwrap is missing, it falls back to the bundled codex-resources/bwrap
binary shipped with Codex and Codex surfaces a startup warning through its
normal notification path instead of printing directly from the sandbox helper.
Codex also surfaces a startup warning when bubblewrap cannot create user
namespaces. WSL2 uses the normal Linux bubblewrap path. WSL1 is not supported
for bubblewrap sandboxing because it cannot create the required user
namespaces, so Codex rejects sandboxed shell commands that would enter the
bubblewrap path before invoking bwrap.
Windows
Legacy SandboxPolicy / sandbox_mode configs are still supported on
Windows. Legacy read-only and workspace-write policies imply full
filesystem read access; exact readable roots are represented by split
filesystem policies instead.
The elevated Windows sandbox also supports:
- legacy
ReadOnlyandWorkspaceWritebehavior - split filesystem policies that need exact readable roots, exact writable roots, or extra read-only carveouts under writable roots
- backend-managed system read roots required for basic execution, such as
C:\Windows,C:\Program Files,C:\Program Files (x86), andC:\ProgramData, when a split filesystem policy requests platform defaults
The unelevated restricted-token backend still supports the legacy full-read
Windows model for legacy ReadOnly and WorkspaceWrite behavior. It also
supports a narrow split-filesystem subset: full-read split policies whose
writable roots still match the legacy WorkspaceWrite root set, but add extra
read-only carveouts under those writable roots.
New [permissions] / split filesystem policies remain supported on Windows
only when they can be enforced directly by the selected Windows backend or
round-trip through the legacy SandboxPolicy model without changing semantics.
Policies that would require direct explicit unreadable carveouts (none) or
reopened writable descendants under read-only carveouts still fail closed
instead of running with weaker enforcement.
All Platforms
Expects the binary containing codex-core to simulate the virtual
apply_patch CLI when arg1 is --codex-run-as-apply-patch. See the
codex-arg0 crate for details.
