Unimpaired picker item

[QiBaobin]

Describe your feature request

As we already remember last picker status, would it be good to add a pair of unimpaired keys (something like [p, [P, ]p, ]P) to navigate to next/previous item in last picker? This would reduce the effort for navigation among workspace searching, buffers, symbols and all other supported pickers.

Note, ]p and [p I am planning to use it to move between paragraph. I wonder if this should be under space buffer or something.
