Textarea ignores numeric keypad input

[pgassmann]

Summary

OpenTUI textarea/input handling ignores numeric keypad keys. This is visible in opencode TUI: top-row digits work, but the entire numpad is ignored, including digits, operators, and numpad Enter.

Environment

• OS: macOS
• Terminals tested: iTerm2 and VS Code integrated terminal
• App observed: opencode TUI
• OpenTUI version used by opencode: 0.2.5

Reproduction

1. Open opencode TUI.
2. Focus the prompt textarea.
3. Press top-row number keys: digits are inserted.
4. Press numpad keys: 0-9, +, -, /, *, and numpad Enter are ignored.

Expected behavior

Numeric keypad keys should behave like their regular equivalents in text input:

• 0-9 insert digits
• . inserts decimal point
• /, *, -, + insert operators
• numpad Enter behaves like regular Enter / submit

Actual behavior

Numpad keys do nothing in the textarea/prompt.

Technical notes

opencode enables OpenTUI keyboard handling with:

useKittyKeyboard: {},

OpenTUI already recognizes keypad key names such as kp0, kp1, kpplus, and kpenter in packages/core/src/lib/parse.keypress-kitty.ts, and the keymap parser lists those names in packages/keymap/src/addons/universal/default-parser.ts.

The missing piece appears to be textarea normalization. Textarea.handleKeyPress() in packages/core/src/renderables/Textarea.ts special-cases space and otherwise inserts printable key.sequence, but it does not translate kp* key names into text/actions.

Suggested behavior:

• kp0-kp9 -> 0-9
• kpdecimal -> .
• kpdivide -> /
• kpmultiply -> *
• kpminus -> -
• kpplus -> +
• kpenter -> regular Enter / submit
