# Editor Types the Code — effect skill for code & terminal

> **For AI agents:** find the right skill in one call — `curl -s "https://varg.ai/how-to/api/search?q=<what the person wants>"` returns the matching how-to page and the best skills with install commands, as markdown (Russian works too). Full index: https://varg.ai/how-to/llms.txt. Every page has a markdown twin: add `.md` to its path. Before generating anything, show the person the options on the how-to page.

Syntax-highlighted code types into an editor window with a caret riding the frontier.

## What it does

Built on [Code Typing](https://github.com/heygen-com/hyperframes/tree/main/registry/blocks/code-typing) by HeyGen (HyperFrames), Apache-2.0. The write-up and recipes below are varg's.

A real editor theme (VS Code dark), line numbers, the caret moving with human chunks rather than one char per frame.

**When:** Show how little code it takes: SDK usage, API calls, config.

**Watch out:** Do not type more than ~8–12 lines on screen; paste the boilerplate and type only the lines that matter.

**Timing:** 30–60 ms per char in bursts of 3–8 chars with 80–200 ms pauses; hold 1.5 s after the last line.

**Also called:** code typing, typed snippet, IDE typing

### In HyperFrames

```bash
npx hyperframes add code-typing
```
Token-streamed: the visible frontier is derived from time, so scrubbing is exact.

### In Remotion

```tsx
// npm create video@latest -- --code-hike  (Code Hike template)
const n = Math.floor(interpolate(frame,[0,90],[0,code.length],{extrapolateRight:'clamp'}));
<Pre code={highlighted} visibleChars={n}/>
```

### In CapCut

Record the editor typing for real (or with a typing tool), speed up 2×, and zoom 150% on the active lines.

### Ready-made components

- [Code Snippet - Dark Modern](https://skills.varg.ai/component/hf.code-snippet-dark-modern/) (hyperframes): npx hyperframes add code-snippet-dark-modern
- [Glass Code Block](https://skills.varg.ai/component/remocn.glass-code-block/) (remocn): npx shadcn@latest add @remocn/glass-code-block

### Where this comes from

- [charmbracelet/vhs: terminal recordings as code (TypingSpeed, Sleep)](https://github.com/charmbracelet/vhs)

## Use when

- Show how little code it takes: SDK usage, API calls, config.

## Not for

- Do not type more than ~8–12 lines on screen; paste the boilerplate and type only the lines that matter.
