[Feature Request] Allow remapping vim-mode insert-exit key (e.g. jk/jj → Esc)

Summary

Claude Code's built-in vim editor mode hardcodes Esc as the only way to exit
INSERT mode. There's no way to remap this to a common alternative like jk or
jj, which many vim users configure via inoremap jk <Esc> in their .vimrc.

Current behavior

• Enable vim mode: /config → Editor mode → vim (persists as

"editorMode": "vim" in ~/.claude/settings.json).

• The only way to exit INSERT → NORMAL is pressing Esc.
• ~/.claude/keybindings.json does not expose any vim-mode actions, so it

can't be used to rebind this.

• Claude Code does not read the user's system .vimrc.

Desired behavior

A way to configure a custom insert-mode exit sequence. Two reasonable shapes:

1. A dedicated setting in settings.json, e.g.:

``json
{
"editorMode": "vim",
"vim": {
"insertExitSequence": "jk"
}
}
``

1. Expose vim actions in keybindings.json (e.g. vim:exitInsert) so

users can bind arbitrary keys/chords the same way other actions work.

Option 1 is simpler and covers the overwhelmingly common case (single two-key
sequence). Option 2 is more flexible but a bigger surface.

Why it matters

For users with years of muscle memory mapping jk/jj to escape, reaching for
the physical Esc key in Claude Code's prompt is a constant friction point —
it's the one vim surface on their machine that doesn't honor the mapping.
Since Claude Code already ships a vim mode, supporting the most common
.vimrc escape remap would close a visible gap without needing full .vimrc
parsing.

Related issues

• #16778 — Ctrl+[ as escape in NORMAL (regression)
• #10621 — double-Esc requirement in Plan Mode Q&A
• #2588 — Enter behavior in INSERT
• #42533 — configurable editor keybindings (covers external Ctrl+G editor,

not the in-TUI vim mode)

None of these cover remapping the insert-exit key itself.
