Ok...please bear with me, as i continue to slowly get familiar with learning PD! 
I've managed to get a working start, using a sendkey VB script graciously written up by someone from the PD forum.  Using bonk~ and moses~, i'm able to split incoming audio to loud and soft levels, which then send commands to open two separate versions of the sendkey vb script - one to type a key for loud, the other to type something different for the soft sound input.  Problem is that the script seems a bit slow - there's a noticeable delay when sending signals from PD to the VB script then to the final program receiving the text strings.  i'm hoping to get speedier results either going the sendOSC route, or by using one of Patrice Colet's external scripts.  i'm including a link to the zipped copy of my PD project from the PD forum:
http://puredata.hurleur.com/viewtopic.php?pid=7514#p7514


So here is my new round of still-newbie questions:

1.  How do i install and use the external scripts winkey and/or kbdstroke?  Or do i need to just call those externals from within pd somehow? 
2.  I'm trying to emulate Dan Wilcox's (aka: robotcowboy's) sendOSC method- i seem to be able to connect to the OSC port, but i don't know how to activate the 'sendkeys' script.  I get a 'no method for 'bang'' error when i try to test with a straight message bang:

sendOSC: connected to port localhost:9001 (hSock=11213640) protocol = UDP
error: sendOSC: no method for 'bang'

Can someone hold my hand and show me how to call 'sendkeys' from within PD to send strings/text to another application?  i'm hoping this method will be faster than the VB script method...

i'm really sorry for hogging up the PD-list with this - i'm getting so close now!  Thanks ever so much for all your collective help!

 Hi I've developped this external for windows last year, this emulate keystrokes, the result of ascii code depends on your hardware, it uses kbd_event API, but I believe the python script from previous messages that uses sendkey would be much better.

 For example ou will have to use messages like this:

[downkey 18, key 9, key 9, upkey 18( to emulate alt+tab+tab combination, .


 Use it at your own risk, good luck.

ooops, I wanted to say "the result of the string sent to the object depends on the hardware"

 and not "the result of ascii code depends on your hardware".

 also if you click on the message that emulate keystroke, the focused window will still be the pd patch because it focuses on mouse release, also the object doesn't seem to work if we use [key] for triggering the message, so I put a delay between the bang and the message, then the message is sent after the mouse click is released.

an example is attached

thankyou
