But I don't expect the shortcut -> filter mapping to be kept, in other words, if you reuse some filters, this changes the shortcut->filter mapping. But if you do the same operations always in the same order, the adequate filter may be assigned to the same key: for instance, in a 3-filtres sequence, hitting the filters-recent-03 key will always elicit the 3rd last used filter, which should be the one to replay at that point in time.
