how when you use a keyboard for a long time the letters wear off or you get a

4
00:00:11,910 --> 00:00:20,039
layer of finger dirt so deep you have to physically scrape your keys well if this

5
00:00:18,510 --> 00:00:24,180
has ever happened to you and you don't have to admit it I'm sure that what

6
00:00:22,080 --> 00:00:29,070
you've noticed is that it mostly affects the keys that you're pressing down all

7
00:00:25,980 --> 00:00:31,500
the time like Eeyore enter so I'd be

8
00:00:29,070 --> 00:00:37,129
willing to bet that for most of you one key that's remained more or less

9
00:00:33,270 --> 00:00:40,320
pristine is scroll lock

10
00:00:37,129 --> 00:00:42,719
but what the heck is scroll lock anyway

11
00:00:40,320 --> 00:00:46,219
is it something people use to keep their documents secure before books were

12
00:00:44,850 --> 00:00:51,600
invented sorry for that anyway we don't need to

13
00:00:49,710 --> 00:00:57,270
go quite that far back for our answer but the scroll lock does hail from a

14
00:00:53,879 --> 00:00:59,430
bygone era of computing these days if

15
00:00:57,270 --> 00:01:03,930
you were working on a document for example you would generally reposition

16
00:01:02,250 --> 00:01:11,369
the typing cursor by moving your mouse and roll the wheel to scroll up and down

17
00:01:07,140 --> 00:01:13,409
the page but back before graphical

18
00:01:11,369 --> 00:01:18,210
operating systems and mice were widespread people used the arrow keys on

19
00:01:16,110 --> 00:01:24,659
their keyboards to move their cursors around or to scroll the page so the

20
00:01:21,689 --> 00:01:29,820
scroll locks purpose was to toggle their arrow keys between scrolling when it was

21
00:01:27,240 --> 00:01:37,079
on and just moving the cursor around when it was off so then is scroll lock

22
00:01:34,470 --> 00:01:42,630
still relevant in the era of mice and fancy gooeys while many people and

23
00:01:40,140 --> 00:01:47,759
keyboard manufacturers are clearly saying no it's not uncommon to find

24
00:01:45,930 --> 00:01:54,899
keyboards without the scroll lock key but that doesn't mean that it's totally

25
00:01:51,420 --> 00:01:58,020
useless some modern programs notably

26
00:01:54,899 --> 00:02:00,380
Microsoft Excel still use the scroll

27
00:01:58,020 --> 00:02:05,460
lock key as it was originally intended turn it off and the arrow keys will

28
00:02:03,270 --> 00:02:10,090
highlight an adjacent cell but turn it on and they will scroll through the

29
00:02:07,140 --> 00:02:15,460
entire worksheet which can actually be handy if you're working on a laptop and

30
00:02:12,490 --> 00:02:19,780
your trackpad is terrible there's also a little-known Windows feature that makes

31
00:02:17,530 --> 00:02:25,180
use of scroll lock if you modify the registry with this key then hold right

32
00:02:22,930 --> 00:02:30,490
control and press scroll lock twice you'll get the blue screen of death cool

33
00:02:27,640 --> 00:02:34,630
right now I'm serious this feature is included to give advanced users the

34
00:02:32,710 --> 00:02:39,600
ability to look at the contents of the system's memory which are dumped to a

35
00:02:36,760 --> 00:02:44,950
log file when a blue screen crash occurs finally if you've got several computers

36
00:02:42,459 --> 00:02:50,020
hooked up to a KVM like in the server room here at Linus Media Group pressing

37
00:02:47,110 --> 00:02:55,990
scroll lock twice then a number key will actually switch the input on most of

38
00:02:52,450 --> 00:02:59,020
these types of devices however as you've

39
00:02:55,990 --> 00:03:03,760
probably noticed all of these use cases

40
00:02:59,020 --> 00:03:05,709
are fringe at best so these days the

41
00:03:03,760 --> 00:03:09,910
most common use of the scroll lock is simply as a free key that can be

42
00:03:08,140 --> 00:03:15,130
remapped for any number of other purposes some people use it to trigger a

43
00:03:12,670 --> 00:03:19,750
macro or some other special function during gameplay while others use special

44
00:03:17,950 --> 00:03:25,450
hotkey software that can repurpose scroll lock as a toggle between two

45
00:03:22,480 --> 00:03:29,170
different virtual keyboards so if you were looking for a way to finally

46
00:03:27,580 --> 00:03:33,220
achieve your life's goal of having a dedicated wingdings keyboard without

47
00:03:31,480 --> 00:03:39,700
missing out on desk space for your regular one this could be the answer or

48
00:03:36,390 --> 00:03:42,070
maybe an alternate Cyrillic or Mandarin

49
00:03:39,700 --> 00:03:45,820
layout would make more sense there's a ton of different reasons you might want

50
00:03:43,660 --> 00:03:50,500
multiple computers maybe use one as a as a coding workstation and the other one

51
00:03:47,799 --> 00:03:54,250
for gaming for example but no one likes having two keyboards and two mice on the

52
00:03:52,330 --> 00:03:59,140
desk it's confusing and it's cluttered well synergy solves that problem at once

53
00:03:56,860 --> 00:04:03,610
and for all letting you use a single keyboard and mouse across multiple

54
00:04:01,180 --> 00:04:10,540
computers even if they have different operating systems all together it works

55
00:04:06,580 --> 00:04:12,450
on Windows Mac and Linux and has great

56
00:04:10,540 --> 00:04:17,820
features including clipboard sharing dragging and dropping files between the

57
00:04:14,709 --> 00:04:20,650
computers custom hotkeys and more

58
00:04:17,820 --> 00:04:24,800
synergy is available in basic and pro versions with the latter including s

59
00:04:22,820 --> 00:04:30,410
cell encryption to secure the data sent between the computers and synergy is
