Cannot bind Alt-/ nor Shift-Tab for [listbox]

[psprint]

I want to obtain the following behavior:
– after invoking a completion either via Alt-/ or Shift-Tab,
– … i want to be able to move to the next matches in the popup list by…,
– … pressing the Alt-/ or Shift-Tab again.

To do this, I bind the Down action in [listbox] section of the keymap file. The logic is that the completion popup is essentially a listbox so binding Alt-/ and Shift-Tab for the Down action should allow to smoothly move across the completion results with those keys.

However, this works only partially and causes problems:
– in the buffer completion, only Alt-/ works,
– in the input completion, none of the bindings works…

I think that those are two separate problems. What can be the reason of them?

Yes, there two separated problems here.
Word completion in editor and path/variable/host/user completion in input line are completely different. And fixes are independent of each other.
