Send multiple modifier keystrokes in one step System
Here's a cool little thing I just discovered. Maybe you all know about it already, but I did not. As an old-time computer user, I have been trained to hit one key at a time, or at most one key in addition to a modifier key. Well, it turns out that it is no problem on the modern Mac to type several keys at once.

I found this out while wanting to bold and underline a word in TextEdit. I held down the Command key, and then simultaneously hit the B and the U keys. Sure enough, bold AND underline. I checked and it works in Mail -- and even in Word! Of course I had to push the limits. Bold, Underline, Italic? No problem. Try that on Windows!

Um...it works in Windows, too.

How did this make "hint" status?

Agreed. I think Rob needs to add one of his comments to this saying that it's not
magic, Mac-only or anything fancy.

But it should probably stand though as I'm sure there are some people who think
that you're supposed to let go of the Cmd key between actions.

Or am I just being too kind?

way too kind. I can't even imagine doing bunch of operations with having to let go
off the modifier keys. Things have been like this for as long as I can remember...
(in all computing worlds, that is unix, mac, windows)

This is ridiculous.

There is no such thing as two simultaneous keystrokes. What happened was
simply that the "Bold" action occured milliseconds before the "Underline" action.

Nevertheless, it also works with command-A and command-C and it appears as if
the mac is going through the keys in alphabetical order so that command-(A+C+I)
will select all, copy it then change to italics but if you paste what is copied it will
still be in plain font.

I don't think alphabetizing is what's going on, you are just lucky you hit them in
that order. miliseconds and microseconds matter in this case, so it's hard to judge.
I just did it bunch of times with cmd+c being activated first (producing system's
thunk sound).

If the system were to order the keys alphabetically, it would imply it's using a
buffer for input and that keystrokes are delayed at some higher level (it would be
stupid to do this at low level), which could be impractical in number of situations
(eg. who's to say your app can't disable command modifiers and you have to hold
down command key to type letters - stupid? yes, but plausible)

Agreed. I tried it umpteen times with command-b and -u in TextEdit and got
Underline to fire first 50% or the time. This is not a hint. It's a discovery of
something that is not a feature.

I agree. One way to rephrase this hint would be this:

Given sufficiently short latencies, humans can trick themselves into believing that sequential events take place at the very same point in time. ;-)

Bold, Underline and Italic?

Typographers the world over are crying into their coffee.

No point giving the original poster a hard time. That person was only trying to help.

It's good that the readers here put their critical thinking skills to use, and test a hint -- sometimes we find, as you did, that all is not as it seems.

(splutter!) That's cool? Well, I suppose it's cool knowing you don't actually have to sprain your hand trying to hit three modifier keys and an alpha key all at once. As a switcher, it strikes me as really odd that Windows uses fewer modifier keys than Mac, which is almost up there with Emacs or something.

That reminds me, is it possible to change key-bindings easily on OS X? I almost never want to clip formatting with text, and in fact the thing I use most often is the aforesaid three-modifier-keys-and-an-alpha for Paste-and-Match-Style, because I'm doing collaborative writing, and cutting-and-pasting between Skype and TextEdit is really <i>awkward...</i> I'd actually reverse it to CMD-V for Paste-and-Match-Style, because I don't want to carry the formatting with it about nine times out of ten.
