## Summary

Documentation for a Windows automation tool's keystroke-injection command, supporting a global `SEND-KEYS-DELAY` directive for inter-keystroke delay ("slow typing" emulation) plus an inline `{DELAY n}` token embeddable directly inside the string being sent, for one-off pauses at specific points.

## Key findings

- Two levels of timing control: a global default delay, and inline per-position overrides — a more flexible model than a single fixed delay for the whole string.

## Pros / strengths

- The inline-token approach (`{DELAY n}` inside the string) is a clean, compact syntax worth borrowing for a tai scripting command, rather than requiring separate delay arguments per chunk of text.

## Cons / limitations / caveats

- Windows-specific tool (keystroke injection via the Windows API), not directly portable, but the *syntax idea* (inline delay tokens) is platform-agnostic.

## Relevance to tai

A good model for the proposal's animated-typing command syntax: support both a default per-character delay and inline markup for pauses at specific points in the typed text, rather than only a single global speed setting.
