A small VS Code extension that runs in the browser (vscode.dev / github.dev) as well as on the desktop. It does two things.

Features

Highlight every occurrence of a word

Select a word with the mouse (double-click) and every other occurrence is marked in the scrollbar's overview ruler. This restores the occurrence markers the full language service normally provides — handy in vscode.dev, where that service runs in partial mode.

Copy files as LLM context (right-click)

Right-click any file or folder in the Explorer to copy its contents to the clipboard, wrapped for pasting into an LLM. Folders are walked recursively and binary files are skipped:

<context>
<file src="src/app.ts">
…file contents…
</file>
</context>

There are two variants:

Copy selected files content to clipboard — contents verbatim.
Copy selected files content to clipboard (compressed) — strips comments from recognised source files (TS/JS, Python, Go, Rust, Java, C/C++, and more) to cut token count, while keeping code, doc comments, and Python docstrings. Data files (JSON, YAML, …) pass through untouched. The result is marked <context compressed="true">, and a notification reports how much smaller it came out.

Settings

Setting	Default	Description
`mouseWordHighlight.triggerOnMouseOnly`	`true`	Only highlight on mouse selections. Turn off to also highlight whole-word keyboard selections.
