shortcut is documented in the instructions.I looked for a KVM system because I didn't have enough room for 4 monitors. I run 2 computers and both have dual monitors (I use Matrox G450 video cards). I set up the KVM system to switch my center monitor between the 2000 and Me computer. My left monitor is the second Me monitor, the right the second 2000 monitor. I changed the desktop colors to make it clear which computer the center monitor was displaying.
I switch regularly by hitting the control key twice. Sometimes there is a delay of perhaps 1 second. The center screen goes black pops back with the other screen.
I loved the color-coded cables and did find the switch box to require two hands - one to hold the box steady and one to hit the switch. I used it to test on the first day and haven't used it since I memorized the double control key shortcut.

Summary: High quality, but a little clumsy
Review: I've used this switch for about 6 months. It's stylish and reliable. The switch and cables are high-quality; image quality is nearly as good as what you see on the much more expensive Belkin KVM switches.
The switch is relatively light-weight; when you press the button to switch computers, you'll likely scoot the switch across your desk unless you hold it in place.
My biggest gripe about this switch is the absolutely insane keyboard shortcuts. Pressing the shift key twice in a row switches displays--just like hitting the button on the switch. The upside here is that it's very easy to switch between computers; the downside is that you'll probably inadvertantly switch all the time! Worse still, the double-shift shortcut isn't documented, and it took me a couple months of frustration with "random switching" to figure out exactly what was going on.
In terms of price/performance, the Linksys KVM unit outperforms all others on the market: The Belkin units offer slightly better picture quality and better keyboard shortcuts, but at a much higher price. The old "Data Switch" KVM switchboxes are less expensive, but the ghosting is so bad that the switch is basically unusable at more than 640x480.

Summary: It's always nice when a product works better than expected
Review: I bought this product to recover valuable desktop space: it works! Since I want both my monitors to display simultaneously, I did not connect the Monitor switch. The reason I decided to write this review was to tell others that the Wheel fuction of my Sony PS2 mouse works using the KVM switch (both in Windows Me and Windows 2000); despite an email from Linksys tech support telling me it would not. I expect that other PS2 Wheel mice would also continue to operate normally. The only reason this is not a five star rating is that the unit really needs to be mounted under the desk because of all the cable connections.

Summary: Great Price, excellent functioning
Review: I needed a KVM switch for a couple of computers that I aquired. I didn't want to pay through the ceiling like the other KVM switches on the market demand. So I flipped a coin and purchased this one. I had it hooked up and running in 5 minutes. It has the option of switching between computers using the button on the actual switch, or using the double ctrl function. Both work great with hardly any noticable lagtime between switches. I have run it on a Win95, Win98 and XP box. I love it, and you can't beat the price!!!

Summary: could of been so much more but still a good deal
Review: Overall I would say its a nice little switch that works very well. Its a good low budget KVM that will work for most home users who just happen to have 2 computers.
My gripes: The hotkey to switch between computers is not configurable. Because there is no software to set up this switch everything is hard wired. So hope you don't use the CTRL key for anything because if you hit it twice you switch computers. Personally this feature I could live without. The button on the switch is enough. I also noticed that since this key is essentially wired to the KVM to switch computers hitting it 1 time has a delay as the switch is looking for the double hit. This is really only a problem when playing games.
Switch does not correctly recognize my mouseman optical mouse. Windows only sees it as a 3 button wheel mouse. It is actually a 4 button mouse and when connected to the switch the 4th button now performs the same function as button 1. Again no software to configure so I am guessing I am stuck with this.
Tech support..well I haven't heard from them yet about this problem. My guess that there is no solution.
Good Points: Cheap, Easy to setup, comes with cables!, no external power supply, and works for most applications.
So I would say it gets 3/5, I would of given it 4/5 if tech support was more responsive. Compared to most other KVM switches you find out there its the best bang for your buck. Most others start at over $100. So if my gripes are not your problem and you don't have to email tech support..give it a 5.
UPDATE: I figured I should update this as I did finally get a resolution from tech support. Their only solution to any problem is basically remove power..try again. The KVM does not support any advanced mouse features such as more than 3 buttons. This is convirmed with tech support. Also I upgraded my keyboard and although most of the programable buttons work if I do the CTRL key switch too fast the KVM switch basically chokes and the keyboard goes dead. Solution..kill power and restart. Somewhat a pain ehh? And that was the answer with tech support. SO my review stands at 3 stars. If you have a cheap keyboard and mouse you should have no prolems. I have had it for almost a year and I do still use it so I just don't use the CTRL key to switch and got used to only using my 3 buttons.

Summary: Made for Convenience
Review: I was currently switching my monitor between the two computers and using separate keyboards and mice. However, it was very inconvenient and I even found myself not wanting to work on something on one computer because I would have to move the monitor. This KVM kit was wonderful. I set it up in no time at all. It came with directions but it is really so straight forward you could hook it up without them. No extra power needed. No batteries or a plug, so it can go anywhere. I have not had any problems with the double ctrl switching feature, but I could see how it could become one if you use ctl a lot. I suggest watching yourself to see if you use the ctrl key all the time. Also, if you don't have cords already, make sure you get this kit(cords included) and not a KVM switch by itself. I have had no problems with lag-time between the keyboard, mouse and monitor. The KVM switch itself has two lights on top that indicate which computer is being used. This is not so useful if you monitor is on, but it is useful if your computer has frozen and you are not sure which computer you are on. I think this switch is incredibly convenient and I would recommend it to anyone that wants to run two computers with just one keyboard, mouse, and monitor.

Summary: Confusing yourself with more than 1 Mouse or Keyboard?
Review: I know I used to use 2 mouses and Keyboards sharing 1 Monitor. If you are one of the serious "Joes" who has more than 1 Computer system, and has one of those old switch boxes for your keyboard, mouse, and monitor. Check this item out for grabs.
The "Linksys ProConnect 2-Port Compact KVM Switch Kit", a 2 port sharing interface with cables included. Yup, I sure did say "cables included". The truth to make things much simpler, it has support for your PS/2 Mouse and Keyboard, which means you don't lose power and control between switch overs.
And don't need to reach over to the switch to make it work, that's right! It has a hot key function, "LCtrl" x2. That's it! You can even put the box hidden or on top of 1 the Systems. Who cares! You'll never see it again once you've installed it. Pretty Cool huh!
This product package with "Ingenius" written all over it is a STEAL!

Summary: Cheap and unreliable
Review: I couldn't get this to work properly, I called tech support and tried a lot on my own (I'm a vetern IT systems engineer so I'm no idiot). This is a cheap piece of equipment and its very unreliable. My problem was a very long delay in keystroke and mouse movement reaction time on the screen. Don't waste your money.

Summary: This product rocks!!
Review: I bought this nearly 2 years ago, and have never been unhappy with it. I've used it on DOS, Windows 3.1/95/98/NT/XP and Linux machines, with PS2-AT and USB-PS2 adapters - - they always work. I tried a Belkin Omniview 4-port switch for about 6 months - finally sold it and went back to my Linksys, which does NOT make an annoying BEEP every time I switch between machines, does NOT care which machine I power-up first, and NEVER gets "lost" between machines. Thank you Linksys!
