Cannot set custom shortcut key (muhenkan) to change keyboard layout

[Alejandro]

Cannot set a single key shortcut to change keyboard layout.
Example in Japanese keyboard:
I can use "shift" + "muhenkan" to cycle through layouts
But I cannot use onlye "muhenkan" to cycle through layouts.

thank you for your bug report. Could you describe what happens when you try setting that key to cycle through layouts?

[Alejandro (aleoliva)]

Sorry for the late reply.
If I set "muhenkan"key only to cycle forward to next keyboard layout it will not change the layout (according to the icon) and the keyboard layout stays the same. If I set "muhenkan" + shift key to cycle forward it will change both the icon and the keyboard layout.

I have tried to set up "muhenkan" to cycle forward and "muhenkan" + shift to cycle backward and it will only work backward. If I immediately reverse the setting to "muhenkan" + shift to cycle forward and "muhenkan" only to backward, then only forward will work.

I have not tried any other combination yet.

Thank you.

What other information is necessary to change "incomplete" status?

[Sebastien Bacher (seb128)]

Not sure, I was trying to help triaging it but I'm not sure what "muhenkan" and how to reproduce/understand the issue described. Setting in back to "new" in case some other triager has more clues on the topic
