Description

Description of the new feature/enhancement

When using ms-terminal, Tab and Ctrl+I send the same key codes. This makes it impossible to map them differently, for example in vim or nvim (which support this functionality: https://github.com/neovim/neovim/pull/17932#issue-1188088238).

If ms-terminal sent different key codes (like for example kitty or alacritty terminal), then it would be possible to map these keys to different functionalities in software running inside the terminal. This would enhance user experience and make it easier to migrate from the aforementioned terminals.

Proposed technical implementation details (optional)

Contributor guide

Research direction
Investigate how other terminals (e.g., kitty, alacritty) implement modifyOtherKeys support. Study the current key handling code in Windows Terminal's input stack (e.g., TerminalInput, conhost input). Understand how key events are processed and where to modify the key code generation.
