0:00:00.404,0:00:02.998
I've noticed something interesting about society and culture.

0:00:02.998,0:00:05.891
Everything risky requires a license,

0:00:05.891,0:00:11.312
so learning to drive, owning a gun, getting married.

0:00:11.312,0:00:14.859
(Laughter)

0:00:14.859,0:00:18.604
That's true in everything risky except technology.

0:00:18.604,0:00:20.963
For some reason, there's no standard syllabus,

0:00:20.963,0:00:22.819
there's no basic course.

0:00:22.819,0:00:24.364
They just sort of give you your computer

0:00:24.364,0:00:26.520
and then kick you out of the nest.

0:00:26.520,0:00:28.647
You're supposed to learn this stuff how?

0:00:28.647,0:00:30.936
Just by osmosis. Nobody ever sits down

0:00:30.936,0:00:32.964
and tells you, "This is how it works."

0:00:32.964,0:00:35.974
So today I'm going to tell you 10 things

0:00:35.974,0:00:39.110
that you thought everybody knew, but it turns out they don't.

0:00:39.110,0:00:41.308
All right, first of all, on the web, when you're on the web

0:00:41.308,0:00:42.954
and you want to scroll down, don't pick up the mouse

0:00:42.954,0:00:45.847
and use the scroll bar. That's a terrible waste of time.

0:00:45.847,0:00:47.920
Do that only if you're paid by the hour.

0:00:47.920,0:00:50.022
Instead, hit the space bar.

0:00:50.022,0:00:53.590
The space bar scrolls down one page.

0:00:53.590,0:00:56.701
Hold down the Shift key to scroll back up again.

0:00:56.701,0:00:58.886
So space bar to scroll down one page.

0:00:58.886,0:01:00.746
It works in every browser on every kind of computer.

0:01:00.746,0:01:04.620
Also on the web, when you're filling in one of these forms like your addresses,

0:01:04.620,0:01:06.982
I assume you know that you can hit the Tab key

0:01:06.982,0:01:08.470
to jump from box to box to box.

0:01:08.470,0:01:11.606
But what about the pop-up menu where you put in your state?

0:01:11.606,0:01:15.222
Don't open the pop-up menu. That's a terrible waste of calories.

0:01:15.222,0:01:19.002
Type the first letter of your state over and over and over.

0:01:19.002,0:01:21.414
So if you want Connecticut, go, C, C, C.

0:01:21.414,0:01:24.310
If you want Texas, go T, T, and you jump right

0:01:24.310,0:01:26.950
to that thing without even opening the pop-up menu.

0:01:26.950,0:01:30.186
Also on the web, when the text is too small,

0:01:30.186,0:01:33.710
what you do is hold down the Control key and hit plus, plus, plus.

0:01:33.710,0:01:36.989
You make the text larger with each tap.

0:01:36.989,0:01:38.923
It works on every computer, every web browser,

0:01:38.923,0:01:40.698
or minus, minus, minus to get smaller again.

0:01:40.698,0:01:43.271
If you're on the Mac, it might be Command instead.

0:01:43.271,0:01:47.375
When you're typing on your Blackberry, Android, iPhone,

0:01:47.375,0:01:50.805
don't bother switching layouts to the punctuation layout

0:01:50.805,0:01:54.269
to hit the period and then a space and then try to capitalize the next letter.

0:01:54.269,0:01:56.487
Just hit the space bar twice.

0:01:56.487,0:02:00.531
The phone puts the period, the space, and the capital for you.

0:02:00.531,0:02:03.822
Go space, space. It is totally amazing.

0:02:03.822,0:02:06.976
Also when it comes to cell phones, on all phones,

0:02:06.976,0:02:10.357
if you want to redial somebody that you've dialed before,

0:02:10.357,0:02:13.069
all you have to do is hit the call button,

0:02:13.069,0:02:16.712
and it puts the last phone number into the box for you,

0:02:16.712,0:02:19.949
and at that point you can hit call again to actually dial it.

0:02:19.949,0:02:21.981
So you don't need to go into the recent calls list,

0:02:21.981,0:02:23.687
so if you're trying to get through to somebody,

0:02:23.687,0:02:24.744
just hit the call button again.

0:02:24.744,0:02:26.146
Here's something that drives me crazy.

0:02:26.146,0:02:28.733
When I call you and leave a message on your voicemail,

0:02:28.733,0:02:30.720
I hear you saying, "Leave a message,"

0:02:30.720,0:02:34.245
and then I get these 15 seconds of frickin' instructions,

0:02:34.245,0:02:37.933
like we haven't had answering machines for 45 years!

0:02:37.933,0:02:40.992
(Laughter)

0:02:40.992,0:02:44.029
I'm not bitter.

0:02:44.029,0:02:46.365
So it turns out there's a keyboard shortcut

0:02:46.365,0:02:48.558
that lets you jump directly to the beep like this.

0:02:48.558,0:02:51.263
Answering machine: At the tone, please — BEEP.

0:02:51.263,0:02:53.401
David Pogue: Unfortunately, the carriers didn't adopt

0:02:53.401,0:02:56.362
the same keystroke, so it's different by carrier,

0:02:56.362,0:02:59.427
so it devolves upon you to learn the keystroke

0:02:59.427,0:03:01.445
for the person you're calling.

0:03:01.445,0:03:03.503
I didn't say these were going to be perfect.

0:03:03.503,0:03:06.705
Okay, so most of you think of Google as something

0:03:06.705,0:03:09.853
that lets you look up a webpage, but it is also a dictionary.

0:03:09.853,0:03:12.582
Type the word "define" and then the word you want to know.

0:03:12.582,0:03:14.192
You don't even have to click anything.

0:03:14.192,0:03:16.649
There's the definition as you type.

0:03:16.649,0:03:18.711
It's also a complete FAA database.

0:03:18.711,0:03:20.681
Type the name of the airline and the flight.

0:03:20.681,0:03:23.253
It shows you where the flight is, the gate, the terminal,

0:03:23.253,0:03:25.413
how long till it lands. You don't need an app for that.

0:03:25.413,0:03:28.165
It's also a unit and currency conversion.

0:03:28.165,0:03:31.013
Again, you don't have to click one of the results.

0:03:31.013,0:03:33.405
Just type it into the box, and there's your answer.

0:03:33.405,0:03:35.590
While we're talking about text,

0:03:35.590,0:03:37.958
when you want to highlight --

0:03:37.958,0:03:41.990
this is just an example. (Laughter)

0:03:41.990,0:03:44.269
When you want to highlight a word,

0:03:44.269,0:03:47.062
please don't waste your life dragging across it

0:03:47.062,0:03:48.701
with the mouse like a newbie.

0:03:48.701,0:03:52.093
Double click the word. Watch 200. I go double click.

0:03:52.093,0:03:53.777
It neatly selects just that word.

0:03:53.777,0:03:56.518
Also, don't delete what you've highlighted.

0:03:56.518,0:03:59.469
You can just type over it. This is in every program.

0:03:59.469,0:04:01.119
Also, you can go double click, drag

0:04:01.119,0:04:04.288
to highlight in one-word increments as you drag.

0:04:04.288,0:04:07.550
Much more precise. Again, don't bother deleting.

0:04:07.550,0:04:12.581
Just type over it. (Laughter)

0:04:12.581,0:04:16.026
Shutter lag is the time between your pressing the shutter button

0:04:16.026,0:04:18.213
and the moment the camera actually snaps.

0:04:18.213,0:04:21.501
It's extremely frustrating on any camera under 1,000 dollars.

0:04:21.501,0:04:23.040
(Camera click)

0:04:23.040,0:04:25.950
(Laughter)

0:04:25.950,0:04:28.475
So that's because the camera needs time

0:04:28.475,0:04:30.323
to calculate the focus and the exposure,

0:04:30.323,0:04:33.083
but if you pre-focus with a half-press,

0:04:33.083,0:04:37.265
leave your finger down, no shutter lag!

0:04:37.265,0:04:39.076
You get it every time.

0:04:39.076,0:04:41.109
I've just turned your $50 camera

0:04:41.109,0:04:43.379
into a $1,000 camera with that trick.

0:04:43.379,0:04:46.979
And finally, it often happens that you're giving a talk,

0:04:46.979,0:04:50.035
and for some reason the audience is looking at the slide

0:04:50.035,0:04:53.491
instead of at you! (Laughter)

0:04:53.491,0:04:56.642
So when that happens, this works in Keynote, PowerPoint,

0:04:56.642,0:04:59.620
it works in every program, all you do is hit the letter B key,

0:04:59.620,0:05:01.989
B for blackout, to black out the slide

0:05:01.989,0:05:04.156
and make everybody look at you, and then when you're ready to go on,

0:05:04.156,0:05:07.403
you hit B again, and if you're really on a roll,

0:05:07.403,0:05:10.244
you can hit the W key for whiteout,

0:05:10.244,0:05:13.371
and you white out the slide, and then you can hit W again

0:05:13.371,0:05:14.644
to unblank it.

0:05:14.644,0:05:17.249
So I know I went super fast. If you missed anything,

0:05:17.249,0:05:19.483
I'll be happy to send you the list of these tips.

0:05:19.483,0:05:21.053
In the meantime, congratulations.

0:05:21.053,0:05:23.643
You all get your California technology license.

0:05:23.643,0:05:24.838
Have a great day.

0:05:24.838,0:05:27.772
(Applause)
