调研方向

报告中没有列出文件、测试或入口点。首先，使用报告中的绑定在主缓冲区和命令窗格中重现原始序列，然后验证命令窗格绑定、非拉丁字符 Alt 绑定以及逻辑上的 Shift-Enter 支持能够正常工作，且不存在重复的原始映射。

    }
}

Description

I've encountered two keybinding bugs while configuring Micro in Foot/Kitty with a Cyrillic keyboard layout. Both issues stem from how Micro parses key events internally versus what the terminal actually sends.

Bug 1: Raw escape sequences are ignored in the command pane

Terminals such as Foot or Kitty send specific raw escape sequences for modified keys. For example, Ctrl+Enter sends \x1b[27;5;13~ and Shift+Enter sends \x1b[27;2;13~.

Using the > raw command, I can see Micro receives these sequences correctly in the main buffer. I can bind them in bindings.json:

{
    "Alt-Enter": "CommandMode",
    "\u001b[27;5;13~": "CommandMode",
    "\u001b[27;2;13~": "InsertNewline"
}

This works perfectly in the main buffer. However, to create a toggle for the command mode, I need to bind the same key to AbortCommand inside the "command" pane type:

{
    "command": {
        "Alt-Enter": "AbortCommand",
        "\u001b[27;5;13~": "AbortCommand"
    }
}

Expected behavior: Pressing Ctrl+Enter while the command bar is open should execute AbortCommand and close the command bar (just like Alt-Enter does when bound this way).

Actual behavior: The raw escape sequence binding is completely ignored in the command pane. Pressing the key does nothing. The command pane parser does not support matching raw escape sequences the way the main buffer does.

Bug 2: Alt + Non-Latin keys require manual raw Unicode mappings

When using a non-Latin (Cyrillic ru_RU) keyboard layout, pressing Alt + a key sends an escape sequence containing the Unicode character of the Cyrillic letter, not the physical Latin key.

For example, Alt+r on a Cyrillic layout sends \x1bк (because 'к' is on the same physical key as 'r'). Micro does not map this to the logical Alt-r binding. To make it work, I have to manually figure out the raw sequence and duplicate every Alt binding (as seen in my bindings.json above):

{
    "Alt-r": "command:toggle ruler",
    "\u001bк": "command:toggle ruler"
}

Expected behavior: Micro should ideally map keybindings based on the physical key position, or at least provide a mechanism to define layout-agnostic bindings so users don't have to duplicate all Alt bindings with raw Unicode codes.

Actual behavior: Users with non-Latin layouts must duplicate all Alt keybindings using raw \u001b<unicode_char> sequences, making the config bloated and hard to maintain.

And a few small requests ...

Feature Request 1: Native `Shift-Enter` support

Currently, to make Shift+Enter insert a newline, users of Foot/Kitty have to manually bind the raw escape sequence (\u001b[27;2;13~) to InsertNewline. It would be much more user-friendly if Micro natively supported the logical binding "Shift-Enter": "InsertNewline" out of the box, abstracting away the terminal-specific escape sequences.

Summary of requested changes:

Fix: Allow raw escape sequence bindings (like \u001b[27;5;13~) to work inside the "command" pane type.
Fix: Improve handling of Alt modifiers for non-Latin keyboard layouts (physical key mapping).
Feature: Add native support for "Shift-Enter": "InsertNewline" without requiring raw escape hacks.
