What it does
Opens a panel, converts text between selected layouts, and lets you copy the output.
Utility
Speed Box: convert a snippet, copy, continue
A small overlay in the browser for keyboard-layout conversion when you are not editing the original field, or when you want a one-off conversion.
Why it matters
Sometimes the text is already typed, pasted, or sitting in a place you do not want automatic rewrites. Speed Box is the explicit conversion tool.
How it works for you
Press the Speed Box shortcut. Choose source and target layouts, convert, copy. Escape closes the panel. It does not require you to understand how remapping is implemented.
Automatic or manual
Manual only. Shortcut: Ctrl+Shift+L (⌘⇧L on Mac). Ctrl+Shift+L / ⌘⇧L
Representative interface. Not a live product session.
What it is not
Speed Box is not a full writing editor, not a translator, and not a spell checker. It converts keyboard layouts.
