Hi Me_again,
The post
Detecting CapsLock State has some background on this issue and shows how one can deal with it...
...but I agree with you that a note or warning should be added to the Help file for Send> to say that the Caps Lock key will affect the output. I also think the few lines of code it takes to detect CapsLock/Numlock/ScrollLock etc. should be there in the help file too.
Before using a command for the first time, I think many of us read about it in the help file. If details like this aren't in there, often we'll learn about it the hard way. Hitting snags is no fun and takes time... however, if its there, no problem and no time wasted.
The vetern macro coders pick up these things through experience (making mistakes) but for new users... how much easier and faster it would be if all things like this were in the help files... just my two cents.
Also... hats off to the folks working on translating the help file. Not only will this bring the documentation to another language, but a lot of corrections and improvements are being applied to the English version as a result, good job all!
