I have the UNO board and I was wondering if it would be possible to use my keyboard to trigger functions on my board?
I am trying to make an alarm clock with arduino and I would like to be able to set it with my computer through the usb cable. [like pressing "S" to display what time the alarm clock is set to go off, then "H" to increment the hour counter up, and "M" to increment the minute counter up.
Is this possible?

You could use it like a stick to press switches.
The keyboard, if it is a USB device, is a USB slave. So, is the Arduino. Two USB slaves can not talk to each other. A slave can only talk to a USB Host/Master.
There are USB Host shields available, and some drivers have been written for some USB devices.
Why not write a sketch that receives characters from the serial monitor and acts on them?
You have to press enter for serial monitor to send them out.
That's pretty simple to implement.

I would be interested in this as an approach. I could see how that could work in code but I am unsure if the USB slave device. Would most likely need to scope it out. I am new to Arduino and an looking at a project with two arduino communicating over ether wifi or FM signal. One ardiuno with a USB touch pad and sending data between the two using something like this link EasyTransfer Arduino Library « The Mind of Bill Porter
My end result would be the target arduino would be taking commands from the primary arduino with attached hardwired USB.
Any thoughts?
ok,
" set it with my computer through the usb cable"
is not the same as
"One ardiuno with a USB touch pad and sending data "
So what's it going to be? Arduino would need a USB Host shield to control a USB touch pad.
Controlling a simple matrix keypad on the other hand is easy.
16, 20 button keypads are also available.
The wireless interface is more straightforward, be it wifi or some other kind of RF.

Yes, it's entirely feasible and very straight forward to do. You need to use an application on the PC to receive your keyboard actions and send the corresponding characters to the Arduino via the USB connection. The Arduino serial monitor provides this capability, or there are various other applications you could use.
On the Arduino side you'd need to write a sketch that read from the serial port and parsed the received characters to work out what command you were sending. Output from the Arduino follows the same path back to your PC for display.
