I'm guessing nobody at Apple wears their WWSJD bracelet anymore, but for everyone else:

Back when I [Steve Jurvetson] was a student, I had Steve Jobs over to my house for a fireside chat with the GSB [Stanford Graduate School of Business] High Tech Club. When I asked my childhood hero if he would sign my Apple Extended Keyboard, he looked a little surprised to see Woz’s signature already there, and then he exclaimed, ‘This keyboard represents everything about Apple that I hate. It’s a battleship. Why does it have all these keys? Do you use this F1 key? No.’ And with his car keys he pried it right off. ‘I’m changing the world, one keyboard at a time,’ he concluded in a calmer voice.

https://archive.nytimes.com/dealbook.nytimes.com/2011/10/06/...

Personally, I would take an Apple Extended Keyboard (or II ;-) ) over anything they've sold in the past, well, whenever they stopped selling them. (Typed from my Unicomp Model M Mac)

Twenty-seven years since Microsoft did so, Apple too wanted a Windows-style key that only they could control.

i always thought that was the command key, it even used to have an apple logo on it. and i thought it was microsoft that created the windows key because it wanted its own key like apple had.

wouldn't you also map the windows key to command when you used such a keyboard on a mac?

That’s all in the article. The author goes into the confusion that it had the Apple logo on it.

Win was conceived as a modifier reserved for the OS (not to be used by applications), while command never was. Command is for commands. If you come to the Mac from Win or Linux it often helps to think of command as what ctrl does on those systems. Ctrl on the Mac started as Terminal-Emulator specific modifier— Which to this day is great, because your universal copy shortcut (cmd-c) and interrupt (ctrl-c) are different things.

Indeed one would map win to command, but only because you need another key for a modifier that‘s not ctrl or opt/alt, conceptually they are different

It did, but when starting history with the first Mac, it started as being absent. The Mac initially had shift, command, and option modifiers.

Apple introduced control keys (separate left and right ones) because companies writing terminal emulators needed it.

Is this where I can complain about command+q? All day every day I use command+tab/tilde/w/a/s, and smack in the middle of that is command q. It's like if automobile manufacturers decided to put a third pedal between the accelerator and the brake that immediately shuts off your car in the middle of the highway. And you can't disable it, instead you can map it to such helpful things like... invert colors.

You can't do that because the design of the whole system is dumb - instead of matching by unique (within the app) universal (=across apps) menu item id like "quit" that's hardcoded into the framework, you must match by menu item displayed name "quit Safari", which is different for every "quit MyNewShinyApp"

PS: and sometimes the name string is also dynamic "Navigate to the latest folder named XYZ", so you can't match at all!

Apple just seems to be in a rush to launch half-baked features then keeps them in a weird state of stasis for years. The globe/FN key changes the keyboard layout when tapped, which is very useful since I type in multiple languages, but after a few dozen uses it simply... stops functioning. It's been broken for years. The only way I've found to fix it is to open the command line and killall Dock and killall Finder. But then language switching fails again a few more switches later. Not fixing a feature that has a whole key dedicated to it just shows how careless they've become.

As a forced mac user at work (always used windows or Linux) the number of modifier keys is really confusing. On pc you use control almost for anything, alt for very special cases (when usually control is already taken) and the windows/meta key for os-related things. On mac a lot of shortcuts use command, but some use control, and there are a bunch that use option without a real reason why, my memory really suffers from this.

The only common thing between the two is that the fn key is only used for the special modifiers under F1-F12.

I was given a magic keyboard, and my plan was to replace it with a standard one, but then I found about the keys mapping from Karabiner, and the fn key is exactly at the control position...so I started remapping.

Now, I can do almost everything with fn+key. Fn+c=command+c, fn+s=control+s and so on.

I was born in the Mac era, but when they still printed the Apple glyph on the Command key. Therefore, I still call it the "Apple key."

I also took inspiration from ChromeOS's replacement of Caps with Search (and a popular article from that era about the history of the hyper key), and rebound Caps to be Escape. I hardly ever use the actual escape key (which is handy on a 60 key board, because they that's just the `/~ key).

Escape (Caps) by itself is Escape. Esc+A is opens the search (goto file/line/etc. in a text editor). Esc+S is the Command Palette in apps that have one.

Very handy to be able to chord keys right next to each other!

Hah, I do the exact same thing for the exact same reason on every new Mac/Win/Linux machine for almost a decade now. Karabiner on MacOS and PowerToys for Windows.

It’s always nice when it’s supported directly in Linux distros but sometimes have to remap it with config files or a helper tool.

On my MacBook I use Alfred now for search and Win11Debloat for Windows which ensures apps load near instantly when typing.

This article covered many historical aspects I was never aware of.

> Suddenly, the globe key on the iPad and the hybrid globe/Fn key on the Mac were equipped with a million Windows-like tasks

It seems like Apple has been in a bind to make the iPad a better Mac and the Mac a better iPad while at the same time insisting that the iPad is its own device with its own purpose and that the Mac is its own device with its own purpose. IIRC, it took a long time to bring a keyboard and mouse to the iPad. Despite Apple’s repeated claims that it doesn’t see value in a touchscreen Mac, rumors point to one being launched next year (albeit with limitations).

Apple used to be good at cannibalizing its own product lines. But now it seems stuck with the desire to sell more iPads and more Macs without one cannibalizing or destroying another.

Arguably only iPhone from iPod.

Lisa to Mac wasn't an organization being "good" so much as corporate infighting ("after Steve Jobs was forced out of the Lisa project by Apple's board of directors, he appropriated the Macintosh project from Jef Raskin") [0].

Low End Mac's "Road Apple" features [1] list out many Apple products that were hobbled in one way or another to prevent a "consumer" product from cannibalizing higher margin "pro" products.

After 2012 Apple's pro desktops did encourage cannibalization by being rarely updated corporate vanity/art projects, which like Lisa to Mac isn't an example of being "good" at managing product transitions.

A more daring Apple would have freed the Watch from the iPhone in the same way they freed the iPhone from iTunes sync.

The article states:

> The Control key is used with terminal-emulation programs for control-key sequences. For all other applications, it is reserved for end-user-defined shortcut key sequences using a macro-key facility.

I find that a good reason. It's prioritizing the experience of terminal emulation programs. Control-C means SIGINT. And also in Cocoa text controls, many Emacs keybindings with Control are available: C-a, C-e, C-k, C-b, C-f, etc. (And it's very easy to add Emacs keybindings with the Meta key too: it's a somewhat obscure functionality but Apple never broke it. I have configured my computer with M-f and M-b for example.)

In the Classic Mac days, control really was just used for custom shortcuts.

That would not be a good approach on Macs where most users are using reduced/laptop keyboards that have no Insert key.

In this respect, Apple got pretty lucky. Most users were not using reduced keyboards in 1987 when they originally decided to add the Control key separate from Command. Plus, Mac OS didn't even have a native terminal at the time; I assume there were terminal emulators for networking/serial use but I can't imagine that was top-of-mind for Apple either.

Regardless, Cmd-C is definitely a more convenient shortcut than Control-Insert, even if you do have the keys for the latter.

I agree with you about Cmd-C being more convenient but that’s besides the point.

My point was that on all three operating systems Ctrl-C has an unambiguous feature: send SIGINT. It is more important to have SIGINT be consistent than have copy be consistent. Accidentally sending SIGINT to a job that has been running for an hour? That hour of work may now be gone. This is a deliberate action that should not be a mistake. Copying is not that? Win+C on Windows doesn’t do any destructive actions.

I think it was in their mind. The manual for the keyboard (yes, keyboards had manuals back then) says the keyboard has “special keys that work in applications running in alternative operating systems” (https://www.cvxmelody.net/Apple%20Extended%20Keyboard%20II%2...)

Not using the combination for one of its ambiguous purposes does not strip it of ambiguity, you've just trained yourself to avoid those circumstances.

That, of course, is one of the pain points that the article addresses: Training yourself to do so is additional cognitive load that never should have been necessary in the first place.

I flip between macOS and Linux and, occasionally, Windows. On one of my laptops, insert is also a Fn switch away, so I have to either remember that this machine needs Ctrl-Fn-F11 specifically when I'm copying from terminal.

On another keyboard I have the same problem, but insert is mapped to a different key entirely, so it is ctrl-fn-equals, and fn is on the opposite side of the keyboard from ctrl.

Contort my fingers in which way on which keyboard? Mental load and annoyance I don't need.

There were "compose" keys that let you type characters to combine other characters -- (not ai) but they weren't forcing the person to super spock pinch the keyboard to get the character they wanted. It was "compose" then "c" then "s" to get the "ç" character.

I honestly would like to be able to do the same thing with ctrl-alt-x, eg. where ctrl alt and x are separate key presses.

I came across this[1][2] the other day; the "bug" is that macOS Japanese input prioritize visually similar but unintended characters over ones matching in pronunciation being entered - it's hard to describe, but it's as if keyboard was autocorrecting word to "enterprising" over "entrepreneur" for entry "antreprenewer", just because the former is considered more common than the latter, or something like that. This apparently has been bugging Japanese users for YEARS, with no improvements or recognition.

I'm not saying who should prioritize what for whom, just that, I think non-English experience in modern computing environment is rapidly degrading lately, for some reason, unbeknownst to American English speakers.

The "compose" key on Linux is one of my favorite things about the Linux keyboard system. You can pick which key is your "compose" key, choosing from about a dozen options. Then just as you describe, you type it in sequence (though on Linux, compose then c then s produces š, because compose then c is the shorthand for the "caron" diacritic: compose, c, g is ǧ, compose, c, h is ȟ, and so on).

Keyboard shortcuts are truly a mess on mac os. Windows does it much better and with more consistency. That results in third party apps also having sensible shortcuts. Example: Ctrl+G is widely used in code editors for "Goto line". On Windows it makes perfect sense to use because Ctrl+ shortcuts are used for text editing everywhere. But on macos it is out of place, because there Cmd+ is the standard for text editing. But Cmd+G is used for some obscure find feature. So editors fall back to Ctrl+G which is out of place.

The "goto line" feature on most Mac text editors is Cmd+L. And it's consistent.

On the Mac the Control shortcuts are used for text manipulation everywhere and they come from Emacs: C-a, C-e, C-f, C-b, C-k, etc. The Cmd key is not the standard for text editing; it is the standard for all app-specific commands. For example Cmd+I usually makes text italic in a word processor, but in a non-word processor app italic makes no sense, so for example in Finder it means bring up the inspector.

I don’t know why this comment is downvoted, but I don’t agree with this either because the OS (historical) conventions are different, and there may be unintuitive shortcuts on all OSes. What matters is consistency across applications on the same OS.

One point on macOS is that it’s very weak on keyboard based navigation and shortcuts for apps by default (compared to Windows). Even Apple doesn’t bother with keyboard based navigation in its own apps. One look at any app “ported” from iOS is enough. Apple hasn’t even spent time to check what the Tab key does in these apps. It’s a shame.

While this is a problem for the default user experience, I think if you're an enthusiast there's less of a problem because you can get an external keyboard you like.

Laptop keyboards will always be disliked by someone: the standard keyboard layout is awful, and dealing with this either involves trying to stick to the conventional design (wherein different people will dislike different changes); whereas a good keyboard design is going to be so far from the standard keyboard that laptops aren't going to do that.

(People will quibble about where to put the arrow keys or however many modifier keys there are or that caps lock is badly placed.. but the most glaring issue is that the spacebar doesn't need to be over 6x the size of other keys).

It's a problem if the OS is inconsistent/unclear about what scan codes are required to do things.

My Mac has no keyboard, it's just a metal box that sits on your desk - so an external keyboard is the only option. Nobody told me I had to get any specific type in particular!

It looks like you can still use hidutil to remap some other key. This invocation seems to remap the Application key to the fn key:

    sudo hidutil property --set '{"UserKeyMapping":[{"HIDKeyboardModifierMappingSrc":0x700000065,"HIDKeyboardModifierMappingDst":0xFF00000003}]}'
On my keyboard, metakeywise, I then have 2 x Shift, 2 x Ctrl, 2 x Option (marked Alt), 2 x Command (marked Start), 1 x undetectable-to-macOS (marked Fn), and 1 x Fn (got that little Windows context menu logo on it).
