 ## Unreleased
 
 ### Changed
-- `peekaboo type` and the MCP `type` tool now default to fast linear typing at 2ms per character; supplying `--wpm`/`wpm` still opts into human cadence.
+- `peekaboo type` and the MCP `type` tool now default to zero-delay linear typing; supplying `--wpm`/`wpm` still opts into human cadence.
 - Hardened the maintainer release workflow around 1Password credential consistency, non-login shells, and neutral-directory npm verification.

 - You can omit the text entirely and rely on the key flags (e.g., just `--tab 2 --return`). Validation only requires *some* action to be specified.
 - Escape handling splits literal text and key presses: `"Hello\nWorld"` becomes `text("Hello"), key(.return), text("World")`, so newlines don’t require separate flags.
 - Without a resolvable snapshot or target process, the command falls back to foreground/global keyboard input and logs a warning that typing will be “blind” because it cannot confirm focus.

 - Background delivery uses process-targeted CoreGraphics keyboard events and requires Event Synthesizing access. Apps that only accept typing in a focused key window may still need `--foreground`.
