comment Can't bind cmd+\ to “Move focus to next window”, but I can bind it to other actions… why?
Not a true answer, but might KeyCue help? Does using the other Command key have the same effect? If you key Command then use Character Viewer to click the on-screen \ key, does that allow the Command-\ shortcut to used where required?

comment Can I downgrade to Mavericks after installing Yosemite?
Some readers may be unaware that OS X Internet Recovery is impossible with some Macs. For my MacBookPro5,2 to regain Mountain Lion (my preference after wiping Yosemite) it was necessary to begin with an Apple DVD for Snow Leopard.

+1 and I'll emphasise this part of Apple's answer: copy any new or changed files. It's as simple, as limited as that; copy stuff. Then a person might try to reuse that stuff, and might get lucky with some of that stuff, but I can't call that a downgrade.

comment OS X Mountain Lion - Kernel Panic and Restart after Sleep
Use an nvram(8) command to add the following boot-arg (boot argument). Then restart the Mac. With this in NVRAM, the next .panic file will be more understandable and informative: keepsyms=y

comment Roll back from OS X Mavericks ( or any newer OS) to Mountain Lion
Migration Assistant in Mavericks explicitly prevents migration from a newer operating system (pre-release Yosemite) – I'll add to the linked question. If Migration Assistant in Mountain Lion can work with Mavericks data, I should certainly treat it as a bug. I can't imagine that the older assistant is designed for that task.

comment Roll back from OS X Mavericks ( or any newer OS) to Mountain Lion
Startup volumes for OS X Mavericks 10.9.4 (13E28) and pre-release Yosemite 10.10 (14A298i) are not recognised by Migration Assistant 5 (521) in Mountain Lion 10.8.5 (12F45). Whether 12F45 can attempt migration from a Time Machine backup of 13E28, I don't know … but considering the nearby answer from @bmike, I should not recommend any such attempt without first fully understanding the possible negative consequences.

comment For bad and/or marginal blocks on hard disks, can anything be more effective than a single pass of zeros?
I up-voted all three answers to my question. The reasons for marking this one as accepted – and for taking so long to decide – are somewhat fluffy, but they include (a) reference to the Tom Nelson article, which is more immediately user-friendly than many others; and (b) opportunities are rare for me to work extensively with a device where a block is weak or iffy. (Recently from me in Apple Support Communities, unfinished: Storage problems, Core Storage, Disk Utility, checksums, fsck_cs and cksum mismatches)

If I could accept two, this answer should be one of two that are ticked √

Thanks. It's possible that bad blocks were successfully reallocated before your run of the software. Now would be a good time to view S.M.A.R.T. data.
