Based on my findings, this is likely not a keybinding issue. It appears to be a conflict in how events are handled:

Scope

1. packages/ui/src/components/list.tsx (line 97-112)
2. packages/ui/src/hooks/use-filtered-list.tsx (line 78-87)

Root causes

1. List component's handleKey passes all keys (except Escape) to list.onKeyDown() from solid-list
2. No check for modifier keys (altKey, metaKey) to skip list navigation
3. solid-list library calls preventDefault() on these events
4. Blocks browser's default behavior for text editing shortcuts (Option+Arrow, Option+Backspace, Cmd+Arrow)

Solution
Add a modifier key check in List's handleKey function (similar to prompt-input) before passing events to onKeyDown().
