4242The command also prints a summary in the conversation, showing resident set size, JS heap, array buffers, and unaccounted native memory, plus any leak indicators it detected, such as a high memory growth rate or an unusually high number of open handles. The summary says whether most memory is in the JS heap, which the snapshot captures, or in native memory, which it doesn't.

44Do one of two things with the output:
44Report the output or investigate it yourself:

4646* **Report it**: open a [GitHub issue](https://github.com/anthropics/claude-code/issues) and attach only the `-diagnostics.json` file, which carries the statistics behind the printed summary and no conversation content or credentials
4747* **Investigate it yourself**: if the summary says most memory is JS heap, open the `.heapsnapshot` file in Chrome DevTools under Memory → Load and sort by retained size to see what's holding the memory

8181In [fullscreen rendering](/docs/en/fullscreen), Claude Code scrolls the conversation itself rather than leaving it to your terminal. If each wheel notch moves fewer lines than you want, run `/scroll-speed` to raise the number of lines per notch and save it, or set the `CLAUDE_CODE_SCROLL_SPEED` environment variable, except in the JetBrains IDE terminal, where Claude Code applies its own scroll handling and neither takes effect. See [Mouse wheel scrolling](/docs/en/fullscreen#mouse-wheel-scrolling) for the values each accepts.

83To move faster without changing the speed, press `PgUp` and `PgDn` to scroll half a screen at a time. To hand scrolling back to your terminal's native scrollback instead, run `/tui default` to switch to the classic renderer.
