Hardware Review: A4Tech Left-Handed Numerical Keyboard

http://www.a4tech.com/ennew/product.asp?cid=100&scid=127&id=424

I recently picked up this unique keyboard online and have been very happy with it. Its distinctive left-handed numerical key layout makes entering distances in Revit a breeze. The keyboard is wireless, comes with a mouse and is very reasonably priced.

It is basically a knock-off of the Logitech Elite Keyboard and has near identical multimedia buttons and features. Although it is a good quality keyboard it is not quite up to par with the Logitech Keyboards. The key action feels a little different and to keep it inexpensive A4Tech left out the Numlock and other indicator lights. The keyboard driver (which isn’t very good) provides Numlock and other indicators in your system trey. I recommend using the keyboard without the driver. Windows XP will recognize the keyboard just fine although it won’t recognize the keyboard’s scroll wheel.

The other unique feature is A4Tech’s proprietary “A” shaped keyboard layout. Supposedly it provides for a more natural hand-wrist alignment, but I think it is more of a marketing gimmick. It does however make the keyboard feel slightly different. At first the keyboard feels a little smaller or tighter than a traditional keyboard, but after a few hours of typing you are not conscious of the difference any more.

The wireless keyboard and mouse come with rechargeable batteries. One innovative thing A4Tech did was turn the receiver into a battery charger as well. I am told that you can go a few months in-between charges. When you do run low, you will always have batteries at the ready. I read stories on the web about the charger overcharging the batteries and causing them to leak fluid. I have also heard this problem has been corrected. I took my batteries out after a day of charging. Although the mouse that comes with the keyboard seems pretty good, I use the keyboard with my own pointing device. The latest incarnation of the keyboard comes with a slick 5-button mouse.

Despite all of its shortcomings, I am absolutely mad about this keyboard. For me it is all about the keyboard layout. With its left-handed numeric key layout, A4Tech has scored a bull’s-eye. I spent last Saturday (my wife thought I was losing it) customizing my keyboard and keyboard shortcuts so that just about all of my commands can be entered from the numeric keys. I even went so far as to write a special key customizing-program to add more keys to the surrounding area. Now with the exception of typing notes my right hand never has to leave the mouse. The beauty of the A4Tech key layout for use with Revit is that everything you need Tab, Shift, Ctrl, etc. is all clustered tightly next to the numeric keys. With your fingers sitting across the 4, 5, 6 keys your thumb falls perfectly on the ctrl key which is a very comfortable and useful position.

I played around with several different keyboard layouts. I tried to group the most used letters and command shortcuts together in logical clusters. The one I finally decided on is basically a modified QWERTY layout I have dubbed the RVT layout. (See attached photo) If anyone has this keyboard and is interested the RVT layout I would be happy to post the layout program and key labels. I am sure all of this sounds like a lot of extra work, but once you have it set up and running, working with Revit is incredibly smooth, fast and enjoyable. Even if you plan to use the numeric keyboard “as is” for the sole purpose of entering distances I would say the keyboard is still a good deal for the money. :D :D :D

I have been temped to do something like this but wonder if it will hurt my other apps... I only use Revit part of the day and have to switch to Max, AutoCAD, Photoshop, Outlook, etc. and don't want to have a custome set up for each one. Do you only use the number pad for Revit?

The little program I wrote to swap the numeric keys around only works when Revit is the current window. If I open up any other application it reverts back to and functions as a normal numeric key pad. It is completely seamless. It is a tiny little program that uses almost no memory so I just put it in my startup directory and have it running all the time. The program is set up so that while in Revit I can easily and comfortably access everything I need (all the commands, snaps, backspace, space bar flipping, left arrow select previous, etc,) from the numeric key pad. The only time I use the main part of the keyboard in Revit is when typing notes. It takes a little time to set up duplicate numeric keypad shortcuts in your “keyboard shortcuts.txt” file, but you only have to do it once. :D

I have just a Targus USB numeric keypad, that I have on the left of my keyboard. I'm still trying to get myself to use it. I think one of the problems is, that it moves! It doesn't match the angle of my keyboard, and moves around enough that it's never quite in the same location. Plus, as i type on it, it moves around. I gotta figure out a way to attach it to my keyboard.

Scott,

I tried the Targus USB keypad and didn't like it for the exact same reasons. I returned it because I found I wasn’t using it. You are right – it moves around a lot and is a little too far away to be of much use. A4Tech’s keyboard is working really well for me. The fact that the palm rest is smoothly connected to the numeric keypad makes a big difference. Another added benefit is that your mouse hand sits much closer than on traditional keyboard.

Scott H,
This sounds great. I have a question though: You seem to be far more technically advanced than I - how difficult would this be for someone with less skill to get up and running? I have installed "inchworm" which allows for using the number pad more efficiently for entering information in Revit but it would definitely be nicer to have the pad on the left as you suggest.

Also, I have used Autocad for many years (2D) and have recently switched to Revit. I am quite accomplished with cad and using short cut keys but am frustrated in Revit, for some reason I can't get them to work properly. In Autocad I rarely take my hand off the mouse or move the mouse off the drawing area. I would love this functionality in Revit. Does anyone have any tips?

Being a ten year veteran of AutoCAD myself, I've felt some of your frustrations as I've made the switch to Revit. All I can say is that the last time I loaded up AutoCAD, I stared at the screen numbly for several moments - I was completely lost.

You didn't really specify why or how the shortcut keys aren't working properly, so I'm not sure if it's a technical problem (i.e. software is broken), or you want to customize them, or what - I know after the switch, I kept hitting the space bar between letters... z space bar e...

If you want to customize the shortcut keys, you can modify the KeyboardShortcuts.txt file that's in the Revit program folder. It's really easy to do. The one that came with Revit8 seemed to have some formatting issues, but there's an updated one around here somewhere on these forums. HTH.

I am the same way. I like to have one hand on the mouse and the other on the keyboard at all times. I do everything with keyboard shortcuts. See the attached post. Download the Revit Keypad 5.0. It has everything you need to turn your A4-Tech into the perfect Revit keyboard. If you choose to go this rout, It will take you a little bit of work to cut the labels and set it up, but once you do you'll be flying.

I just purchased a Logitech MX610 left handed mouse.It works great to use the mouse in my left hand which leaves my right hand free for the numeric keys and arrow keys. The mouse has 10-buttons that can be programed.
