I successfully moved anagram questions with both former and new anagrams into cardbox 0, so they will be scheduled sooner.
Here's how:
After following Richard's steps for moving your cardbox from your previous Zyzzyva to Collins Zyzzyva, you can add new words to the cardbox in the usual way by including a condition for not in lexicon CSW12 in any search, and right clicking the list to add those words to your cardbox. HOWEVER, words with formerly acceptable anagrams (e.g. ANODISER+ / ANEROIDS / DONARIES (#)) will remain at their current schedule and cardbox, and may not be quizzed for a long time. To address that issue, do the following, but be careful:
Tools / Reschedule cardbox contents / Shift words so that this many are ready (use a number big enough so ALL questions will be ready - after the reschedule, Zyzzyva will tell you how many questions were rescheduled, and that number is the total number of questions in your cardbox)
Now start a new quiz, method: cardbox; question order: schedule; Use only words matching specification; Include the condition In lexicon NOT CSW12, and whatever other conditions you want. I do one length at a time, and might split by probability depending on how many come up. If you have already added new words to your cardbox, you may want to add Number of anagrams 2 or greater, to exclude some of the new words you've already studied.
Click through the quiz quickly, INTENTIONALLY MISSING every question. This throws all of these words into Cardbox 0, HOWEVER, they are not yet scheduled correctly, because you still need to reverse your rescheduling, and that will move these temporarily due soon questions, to not due for a long time.
Now Tools / Reschedule cardbox contents / Shift words so that this many are ready - 0 (Honestly, really use zero, you can reschedule again later if needed)
Now start a new quiz, method: cardbox; question order: schedule (Cardbox 0 first);<-- IMPORTANT you will have to change this; Use ALL available questions
This should bring up a quiz with just the questions you forced into Cardbox 0 along with any other questions that were in Cardbox 0 before you started.
Now go through this quiz, as a quiz, and whether you miss them or not, they should now be scheduled in the near future.
