Is Caps Lock Dead? 1206

Posted by timothy
from the remapping-is-the-answer dept.
An anonymous reader asks "Recently I have noticed that I haven't used caps lock other for any purpose other than hitting it by accident. Once upon a time, COBOL was written in all caps, and other languages like BASIC and Fortran were not case sensitive. Capitals were the way to go for writing code. Does the caps lock key serve any purpose any more, and if not, should it be removed, moved, or replaced?"

    Well, as I am using a mixture of Debian/Sid/Experimental and lots of unstable (and non-official) packages, my system freezes once in a while. However, pressing Caps Lock helps me check if the keyboard driver is still live (so that I can use the MagicSysRq Keys) or I must reboot by hand. Could use NumLock for that matter, but CapsLock is usually nearest to one of my hands. The truly useless key is ScrollLock, BTW...

    Actually, in the US Navy and other branches of the service radio messages all always in all caps. These were a pretty routine part of life on ship (for Officers / admin personnel etc) We would compose the messages on a PC w/ word processor, print hard copy, then have approved by CoC. Radio men would send them out encrpyed, hard copies were always kept for paper trail. A ship my send dozens or even hundreds of these a week, so the're quite common. There are a few who may need cap locks who aren't programmers. M

    Here's how I made capslock an extra control in Windows 2000/XP.

    Go to this path in the registry editor:
    HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Keyboard Layout

    In that registry path, add a new binary value, like so:
    Name: Scancode Map
    Type: REG_BINARY
    Data:
    00 00 00 00 00 00 00 00
    02 00 00 00 1D 00 3A 00
    00 00 00 00


    This required a reboot to take effect (for me, anyway).

    It's still useful for situations when you need to type something in all-caps with one hand. Take your mind out of the gutter.

    I'm not a touch typist, and I often just use my right hand to type, leaving the other hand free for holding books, documentation, operating equipment, etc. Caps lock is useful when I have to type in hexadecimal constants, or source code that is all in upper-case (FORTRAN, Assembler).

    uControl [gnufoo.org] is a nice little Mac OS X hack that disables/remaps Caps Lock and other modifier keys on PowerBooks.

    I also used it to remap the "Enter" key to the right of the spacebar on my 15" TiBook to "Command" -- I have no clue why Apple thought that was a good idea, but uControl saved the day.

    It's very well designed -- if it thinks there's going to be a conflict when booting into an upgraded OS it will disable itself (vs. barfing and causing a system panic...)

    Some people actually know how to type, which means they use all the fingers on both hands to reach the necessary keys. More to the point, it means that holding down the shift key with one finger while trying to touch-type puts an odd strain on the hand and is poor typing posture. The shift key should only be used for at most 3 letters in sequence, and probably should be avoided for more than a single capital letter in a word.

    Apple has done this already.

    It's right above the delete key in place of the infrequently used insert key.

    Unlike the PC makers' latest trend of adding a bajillion buttons to the keyboards that will never be used, apple added four buttons above the numlock pad in place of the "lock" lights (which in place are located directly on their respective keys). The four (incredibly useful!) buttons are:
    Volume Down
    Volume Up
    Mute
    Eject Disc (less useful than other 3, especially if you have more than one optical drive. Still, since Mac OS requires a software dismount, it's necessary.

    Oh yeah... did I mention that it has a USB hub in it? Why the hell are we still shipping PCs with 12-year-old PS/2 technology?

    I just miss the power button. Even so, apple's relocated it to the monitor (another thing PC makers should have done years ago), which in my mind is the 'proper' place for the system's power button.

    I'm a navy reservist, and although the Navy and the other branches of the armed forces are moving towards computerization of almost every aspect of information management, oft times you'll find that because of some arcane requirement for filling out a form or other type of data entry, you're required to use all caps. However, in many cases, the program that was written to replace forms with this requirement won't enforce the capitalization, much less actually automatically capitalize everything. You say it's dumb, I say it's dumb, and all the staff we have say it's dumb. But, in the mean time, they have to live with it, and having the caps lock key makes it all the more bearable.

    All typewriters have CAPS LOCK. Thus,CAPS LOCK was not invented for programming, just for typing. Besides, less than 1% of computer users are programmers. This is a tiny minority which is irrelevant. The question is if the majority of computer users want to have it removed. I think the answer is no: Typewriters had CAPS LOCK for over a hundred years, why should it be removed from computers?

I find it a bit silly because one person hasn't used it, it must mean that no one else does. Sure, home users might not find much use out of it, but in the business world it is used everyday. And the business world makes up the majority of PC sales in the world.

    "Now, I'm not saying that it's NEVER used by ANYONE, because I'm sure someone will reply and tell me that it does some obscure function in some obscure program."

    Only if you consider *nix an obscure program. Scroll lock in those (at least those that I've tried it in, which means a couple different flavors of Linux and FreeBSD) stops the screen from scrolling so you can read it. FreeBSD will even let you scroll up with the arrow keys so you can see text that has scrolled off the screen. It's actually quite useful. (For instance, you're maknig something with dependencies and a message comes up that you should actually read but it starts to compile the next thing, you can still read it. Also removes a lot of the benefit of piping stuff to more or less.) I would imagine there's a way to set this up under Linux too, but I haven't yet seen a distribution that has it working out of the box and I don't know how to configure it.

    My company uses and resells a backoffice application called SouthWare [southware.com]. It's used by hundreds of companies throughout the United States on both *nix and Windows. The Acucobol source code (which our company has licensed for modifications) is written in all caps, and the software itself requires all caps for operation.

    It's roots date back to 1984 when COBOL source code was always written in caps, and to change it would require rewriting almost 2,000 object files.

    So the need for a caps lock is still very much alive...

    If you're going to get rid of a key, maybe scroll lock would be a better one. I don't think I've ever actually seen anyone use it for anything besides playing with the pretty lights.

    I use it every day - it's a common shortcut key for KVM switches (Belkin, at least). Scroll Lock - Scroll Lock - Machine #.

    That's still somewhat a testament to it's uselessness though. I'm fairly sure the KVM makers thought to themselves "we need a shortcut key on the keyboard... one that is almost never used for anything else..."

    The capslock key is used by some non-English input methods to switch back and forth between English entry and the other language. I found out about this when I kept noticing that my fiancee left the caps lock key on for me when I would use her laptop. In Traditional Chinese entry mode the caps lock being on puts you back into English entry mode. So I very much doubt, since the Chinese make um what 99.99% of all keyboards, that they will be removing the capslock key. :-)

    Oh yeah... did I mention that it has a USB hub in it? Why the hell are we still shipping PCs with 12-year-old PS/2 technology?
    Easy. Because USB is not a perfect replacement for PS/2 input devices.
    • There is a large amount of latency on the USB bus as well as software latency incurred due to processing the USB packets. There is practically no wire latency with PS/2 and the protocol is dead simple to parse. You can create a little microcontroller project to interface almost any simple device to a PS/2 port. With USB, you need a separate ASIC to even begin to get anything done.
    • USB controllers typically share interrupt levels with other PCI devices. On systems without an IO-APIC, this translates into increased software overhead on every interrupt, because the interrupt handler for every device sitting on that interrupt is invoked. Whereas with PS/2 devices, you have an IRQ reserved for the keyboard and an IRQ reserved for the mouse. Since they are edge triggered ISA interrupt lines, there is no possible way for them to be shared even if you wanted to. Therefore the correct interrupt handler (and ONLY the correct one) is invoked in response to a PS/2 event.

    In short, there is no possible way on any but the fastest of current machines for a USB mouse to approximate the responsivity of a PS/2 port mouse being sampled at 200Hz (the maximum rate the port will tolerate).

    The behaviour of the caps lock key on ADB keyboards (like those built in to all apple laptops) is a bit broken, as it does not send a normal key release signal to the keyboard handler. This means that considerable trickery is required to correctly map caps lock to a modifier key.

    Caps are more easily readable on envelopes, some database and spreadsheet entries, titles of chapters, and many more writing applications.
    I work with several different databases. All of our database data is stored in caps. Why? In decreasing order of significance:
    • Postal Service Discount Requirements [usps.gov] - Unless you like spending lots of money on mailings, use one of the discount mail formats, such as automatable mail. Automatable mail means CASS cerification, which means using all caps. Otherwise, the best bet is using an all-caps, 8-18 point sans serif, uniform stroke width font, 3/4 to 3 point space between characters. We found that 10 or 12 point ariel fits the requirements. If you use bulk mailing and you don't fit the requirements, the mail can be thrown out, not returned, so you wouldn't know that your mixed-case address had problems.
    • Compression size - Your compressor should notice that almost all the data are of about 30 values {0-9, the common A-Z values, space}, and a few other symbols for the database system. That tiny alphabet, and considering the rarity of certain alphabet letters, will make dynamic huffman VERY happy. Mixed case would at least double the size of the compressed alphabet, meaning larger backups. If you do backups (you do, don't you?) it helps. If you have to distribute the database to different sites, it really helps. In one example I encountered recently, the client had about 6 GB of compressed data and wanted to send it to all of their stores nightly. Each store is equipped with a dedicated high-speed line, but 6GB daily (over 9 hours on dedicated T1) is too much for a nightly transfer. After looking at their data, simply converting everything to caps let it compress to just over 1 GB of data (under 2 hours over a T1 network).
    • Uniform - It's easier to search for names that some people like to have different capitalization rules on (Shrudili/ShruDili/ShruDiLi, MacKay/Mackay, etc) Yes, you can do a case insensitive match (you insensitive clod) but it takes more CPU work; That's bad when a batch run already takes a long time for simple case sensitive matches.
    • Readability - It's much easier to read names and addresses on the screen when they aren't mixed case.

    The first one will save you lots of money in mailing. If your company is in to saving money, then your mailing lists already do that. Compressability of data is *very* important for large-scale systems, and can have significant improvements with an ALL CAPS DATABASE. The last two just help reduce system load and operator error; both are good things to reduce.

    "Readability - It's much easier to read names and addresses on the screen when they aren't mixed case."

    This puts you in the minority. I have worked with readability (mostly related to layout, contrast and fonts), and to the overwhelming majority of us all caps text is significantly more difficult to read than mixed or even lower case text.

    And if your compression algorithm compresses all caps text twice as much as mixed case, your compression algorithm sucks. Text is not random characters, it contains a lot of compressable repetitions, the very small portion of these that are affected by mixed case is negligible.

    Yes, dear slashdot-readers, contrary to your assumptions there are some parts of the world in which other languages than english are written.

    I for one have a keyboard featuring keys labelled ö/é, ä/à and ü/è for writing german and french. And of course, the only way to get Ö/É, Ä/À or Ü/È is capslock.

    Even better, with my capslock turned on I get a load of special characters like this:

    @ØÆßÐK""

    Cool eh?

    you want an old Sun keyboard. they had two columns of five (six?) keys on the left hand side. i don't remember all of them, but they included at least cut, copy, paste, select, and help.

    so, somebody has thought of this. the issue was that less and less apps could be bothered supporting them over time, in the face of the fact that not everyone had one of these keyboards and everyone had key-combination shortcuts. there's also a good reason why they were alternately called the Sun Battleship Keyboard or Sun Aircraft Carrier Keyboard - they were friggin' huge.

    Typing in British and Canadian postal codes is about the only time I can think of that I use the caps lock key. British codes look like:

    LN6 2QJ

    while Canadian ones look like:

    N2M 5E5

    The caps lock key has the avantage over the shift key in that it doesn't affect numbers. If I use the shift key, I tend to end up with something like:

    N@M%E%

    unless I'm very careful.
