Back in the Keyman 5.0 days, you had to hunt for keyboard files (.kmn) on forums. Now, Keyman includes a built-in downloader with hundreds of free, curated keyboards. Search by language name or country, and install with one click.
Never guess key positions again. Keyman 50 includes a real-time on-screen keyboard that highlights the active layout. This is invaluable for learning new scripts or typing in uncommon characters without memorizing key combinations.
The "Tavultesoft Keyman 5.0" package sometimes included a basic editor. Today, the free Keyman Developer lets you build your own keyboard from scratch using a visual interface or XML. This is how missionaries and linguists create keyboards for unwritten languages.
