set key command

Im looking on more information on how to use set key in scripts. can any one point me in the right direction.

setkey <keyname> <up or down>

So if you wanted to press enter, you could make an enter.txt script:

setkey enter down;wait 0.2;setkey enter up;

ty,  how would ctrl+k work. or alt+1

I haven't worked with setkey myself, but I don't think you can do a combination of keys. You'd probably have to do ctrl first and then k, then release both
