Ukelele overview
Ukelele is a Unicode keyboard layout editor for the XML-format keyboard layout files in OS X (".keylayout" files). It provides a graphical interface to the layout files with support for drag-and-drop character assignments, creation of dead keys, and assignment of multi-character strings.
Ukelele is not able to reassign modifier keys (Option, Shift, Command, Control, caps lock), or change the function of special keys (Return, arrow keys, function keys, etc). Rather, it is for creating keyboard layouts for different languages or other needs.
By the way, the name of this software is intentionally misspelled (try pronouncing it "You-KEY-lay-lay"). Call it an instance of 'artistic license'.
What’s new in version 3.6.1
- Prevent creating a key output longer than 20 UTF-16 code units, which is the limit imposed by Apple.
- Avoid a crash when using the key pane to change output and dragging text to a different key cap.
- Updated the Unicode database to version 17.0.0.

Hi, I would modify my US MacBook keyboard. But when I start the process, New From Current Input Source loads a full keyboard with numpad. MacBook has no numpad. How can I load the native MacBook keyboard on Ukulele?

Save as... doesn't work. I deleted one saved file and wanted to resave it as a bundle.... I was lost and 1 h work to. Crap GUI programming here.

It's a wonderful little app helping enormously to customize the keyboard mainly for layouts with uncommon diacritics. Thanks a lot!
