That's more charitable. Alt is still short for Alternate though, not Alter.

I thought "Alt" in the title is meant in the sense of "stop", as in "halt", but on second thoughts maybe that only works in French (where h is always silent)?

It's clearly meant to be part of the Ctrl-Alt-Del key sequence that interrupts Windows computers to bring up the task manager.

But doesn't Ctrl+Alt+Del bring up the screen to switch users or sign out? "Task Manager" is one item in the list of options you get, but it's not the main one or anything, in fact it's the last:

The author may just be showing their age a bit. That's what Ctrl+Alt+Del does on modern versions of Windows, but from Windows 95 to Windows XP (inclusive) it directly launched the Task Manager.

Would have made more sense to say Ctrl+Shift+Esc since that just directly brings up the task manager. All in all I would say it is a slightly weird title, but I assume enough people get what they want to say with it.

I mean, technically it’s short for alter on the way to being short for alternate

That's bullshit (IMO) and the post author (Phillip Torrone - I believe that's one of the owners of Adafruit) is obviously ignorant in this regard.

That said, what he's actually talking about in the post makes a lot of sense. That is the important part.
