LoadUI/SaveUI does not include Keybindings. It only includes your actual UI elements. To save and load your keybindings across different characters you need to use a slash command.

/bind_save - to save to a default file name
/bind_load - to load from the default file name

/bind_save_file c:\path\to\save_file.txt - Save to a file name of your choosing
/bind_load_file c:\path\to\save_file.txt - Load from a file name of your choosing
