using modifiers when mapping fn function key seems to fail

[joeldcanfield]

Successfully mapped some fn keys to open various apps. Trying to map F3 to left-arrow+left-shift+left-command+left-option and it fails.

Karabiner seems to refer to the command key as both command and gui, and the option key as both option and alt. None of these results in anything except the left arrow key when I press F3. Virtually identical issue with mapping F4 to r+modifiers. Seems to simply ignore the modifier keys.

{"from": {"key_code": "f3"},"to": [{"key_code": "left_arrow","modifiers": ["left_command","left_control","left_alt"]}]}

{"from": {"key_code": "f3"},"to": [{"key_code": "left_arrow","modifiers": ["left_command","left_control","left_option"]}]}

{"from": {"key_code": "f3"},"to": [{"key_code": "left_arrow","modifiers": ["left_gui","left_control","left_alt"]}]}

{"from": {"key_code": "f3"},"to": [{"key_code": "left_arrow","modifiers": ["left_gui","left_control","left_option"]}]}

THESE WORK AS EXPECTED:

{"from": {"key_code": "f1"},"to": [{"shell_command": "open '/System/Applications/System Preferences.app/'"}]}
{"from": {"key_code": "f2"},"to": [{"shell_command": "open '/System/Applications/Messages.app/'"}]}
{"from": {"key_code": "f5"},"to": [{"shell_command": "open '/Applications/Affinity Photo.app'"}]}

Mac using KEv14.10.0

I seem to have the same issue. I confirmed with Event Viewer.
