Broken: example: 2.78
Worked: >new feature request<
Short description of error
when spacebar search menu popups and user start writing the required command, only down-arrow keyboard shortcut are allowed to select the required command, starting from first item on top.
It will be very useful and faster if also up-arrow can be usable to select the last item in the list (so starting from bottom).
See image as reference: green arrow show the required feature, red one is the only one actually working.
Exact steps for others to reproduce the error
not an error, only UI usage improvement :)
