Q:How can you create symbols on a regular keyboard.
Unicode symbols are typically made by holding Alt and using a combination of the number pad keys. You can look up combination lists online.

Q:I need a laptop keyboard, my space bar is broken ,and I am selling it so I need a new laptop keyboard ,where can i get one? its a Compaq laptop, btw.
you could call customer service and tell them you need a new keyboard, they will ask you the model of you computer and have you ship it to them so they can replace the keyboard.
Q:Did i lock somthing how do i fix it . right now im using onscreen keyboard, here is the alaphabet ysig keys abcdfghjklmnstvxyz thn more
Keyboards will eventually go bye bye. Unfortunately you will have to either live with it or buy a new keyboard. Otherwise you could try air-dusting the keys.
Q:1 how does a DVORAK KEYBOARD layout is closely in competition nowadays with the QWERTY KEYBOARD Layout in terms of popularity of use. 2 What are the advantage and disadvantage of the DVORAK KEYBOARD and QWERTY KEYBOARD?(I NEED IT FOR MY RESEARCH)THNX!
I wouldn't know how competitive Dvorak is to the Qwerty keyboard but since it is rarely used, a big disadvantage to using Dvorak is that it is hard to use any other computer without your layout. Some other cons would be that it takes awhile to learn a new keyboard layout and most laptops only come equipped with Qwerty. And I would know from experience that Dvorak does allow you to type faster, since your most commonly used keys are the eight buttons you rest your fingers on. It really helped me to touch type, because I was able to memorize the keyboard since I couldn't constantly look at the keys since I was using a Qwerty board.
Q:I have heard that, in order to understand Chinese, you must learn at least 3,000 characters. How big of a keyboard would that be?Our keyboard is about a foot long, and we have 26 letters, so a Chinese keyboard must be about 115 feet long!But seriously, how DO they type Chinese?????
You could type Chinese on your keyboard if you wish to. Chinese keyboards are exactly the same size as ours. There are various methods of typing Chinese. You can type by entering pinyin, or you can type phonetically (Chinese is made up from monosyllables) - there are various methods of typing. Only difference is that Chinese keyboards may have small characters next to each letter.
Q:I have a dell desktop. And an hp ps#92;2 keyboard connected to it via a gigaware usb adapter. Yesterday it randomly stopped working. When computer is powered on or i plug the keyboard in. 3 led lights blink twice and then nothing. Ive tried restarting the computer. Plugging it into different usb ports. Everything i can think of. Someone help please?
Have you tried plugging the keyboard directly to the PC keyboard port and not thru the adapter?I'm assuming the desktop has a P/S2 port. If yes, then it is possible the keyboard is drawing much more power than the USB ports can provide. Try the following: 1. Check to see that all pins in the keyboard connector are straight and none broken 2. Use a different USB adapter If none of these works, you probably have a dead keyboard.
Q:I am considering buying a laptop but find it difficult typing on the flat keys of a laptop keyboard. Can you plug a regular desktop keyboard into most laptops to type on?
yes although, it can be tricky look for a USB keyboard or full sized keyboard specifically made to be used for a laptop. as many laptops will not have the ps/2 port that a traditional/old keyboard utilizes. there are tiny gizmos that are convertors. ps/2 to USB that often come with keyboards. but make sure it does, if you're getting a keyboard of that type. as far as how it'd exactly work once connected to your laptop i'm sure it's a simple matter of going to control panel/keyboard and making sure the new keyboard is there and or switching to it. Or it may just naturally recognize itand you do nothing. would depend on the laptop.
Q:I think gaming keyboards are very expensive. Is there anything to it besides Backlid keys / Programmable keys. Because i do not need any special stuff i simply dont care. Is this the only reason people get gaming keyboards?? Should i just go with a normal keyboard instead. Or will that hurt my gaming performance. ( Once again i am not talking about programmable keys and stuff ) but response time maybe. Can anyone recommend me a good non-gaming keyboard for below 20 ?
A gaming keyboard won't make your K/D better, don't worry. If you don't care about gimmicks just about any keyboard will do. I'd advise not getting a REALLY cheap one though, they tends to break fairly quickly. Logitech make good stuff, and not to expensive either.
Q:1. I played the violin but don't really want to anymore, so which should I do, violin or keyboard?2. How much is a rental keyboard?3.My friends mom teaches piano, would she also be able to teach keyboard?
I play all three, Guitar, Piano and Violin. I learned Piano and Violin when I was young. I like the Violin also but it will never give you the satisfaction that playing piano will. Piano also teached music theory that will help you with the Guitar. It may be easy to pick up the Violin since you already are used to fingerings and having one hand move opposite to the other. Violin is OK if you are going to use it somewhere, otherwise I hardly ever play it . I can sit at the piano and amuse myself for a long time. However, playing Guitar is the best, how cool is that?
