Selected key input delay

I have a "seven finger" typing style. I move very fast with my strokes..too fast on some. For example, I tend to input the word "the" as "teh". I also will think I am typing "and" or "because" and they come out "nad" and "becasue". This happens in many other words. I videoed my typing and played the video in slow motion to find out why this is happening. I know in my mind I am spelling these words correctly. But, my fingers are "stepping" on each other by habitual too-rapid strokes I have found it impossible to correct unless I very dramatically slow down my typing speed. In watching the slowed video, though., I had an idea. What if I could deliberately show down a key's input signal after I hit it- that is buffer it somehow on the keys I am having trouble with. In analysing my writing errors, I found the only offending letters are the vowels 'a', 'e' and 'u' and the consonant 'n' with an occassional 't' and 's' being an offender. Few words using the rest of the letters get mixed up. I decided that if those letters could somehow be delayed by mere milliseconds before their actual input, my typing errors would dramatically decline. As you can see, if the error keys are some of the most used letters, R,S,T,L,N,E, then, correcting those errors would be a big step in the right direction.

So, the idea is, to create a typing input adjustment thingy in which the typist could install tiny thousands of a second delays between actually hitting the key and it being inputed to the prosessor. This delay would help stop my overly eager finger inputs, letting the proper sequince of my intended letter selection be placed in my writing.

Now, I know that spell-check can help and it greatly does in some of the word processors. I have built quite a correcting vocabulary and I do very well with writing in processors like Word and Works and so-forth. But, some places on the net, like my e-mails, various blogs and discussion boards don't have spell-check and so far I have not found how to make everything I type no matter where I type,to filter through my spell check setting (if there is a way to do that, my idea is kaput...I know)

But, it seems to me, this would be a great way to vastly imporve one's typing accuracy in working on computer keyboards..a kind of super smart keyboard (ha- I just typed that as "keyborad" and the word 'just' came out as 'jsut'- well at least I have a backspace key.)

Am I half baked or is this a good idead?
