As foreign Mac users, we always use input method to enter text.
In many input methods, direction keys (most as uparrow and downarrow) are used to select words or characters for the corresponding language.
However, when we enter the text by input method in the fallback results field, the direction keys are captured to select the fallback actions other than the words of input method.
This phenomenon occurs always and is quite distracting. Conversely, in Spotlight, the words' selection for input methods is always prior to the selection of actions.
There is no doubt that the Alfred users in many countries are suffering from this bug.
Please let us know any further information of the debugging process at your earliest convenience.
