Walkthrough

The pull request introduces a change to the Editor.tsx file by removing the Vim key mapping that allowed users to exit insert mode using the 'jj' key sequence. This modification affects how Vim users interact with the editor, as the previously available shortcut is no longer functional.

Changes

File	Change Summary
frontend/src/components/editor/Editor.tsx	Removed the Vim key mapping for 'jj' to '' in insert mode.

Possibly related PRs

• Reorder keybinding addition for VIM in CodeMirror6 #346: This PR modifies the initialization of the Vim extension in the Editor.tsx file, which is directly related to the handling of Vim key mappings, similar to the removal of the 'jj' mapping in the main PR.

Poem

In the editor's realm, a change took flight,
The 'jj' shortcut vanished from sight.
Vim bunnies hop, searching for keys,
In the code's gentle dance, we find our ease.
Though the mapping's gone, we'll adapt and play,
For every new path leads us on our way! 🐇✨

4-4: Please provide more context on the changes related to the Vim mode.

The import statement for the vim module does not seem to be directly related to the issue described in the PR objectives. Can you please clarify how this import statement fixes the problem with entering jj in Vim mode?

Additionally, the AI-generated summary mentions that the Vim key mapping for jj to <Esc> in insert mode has been removed. However, this change is not visible in the provided code. Can you please provide the relevant code changes that remove this key mapping?

More context on these changes would help in understanding how they align with the PR objectives.

  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:

  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
