Swap keys, please

if you want swap keys.
do this:

key_x to key_y
key_y to key_x

thats it

well, thats in my understanding "swapping keys" in a perfectly
adequate manner.

i cant understand the statement it would be impossible to swap keys.
because its totaly confusing.
the only thing you can _not _do, and thats whats obviously related to with the "impossiblity to swap keys",
is the direct command in one line to swap keys:

Caps Lock to Left Ctrl ( "swap now, please" )

i think this is a good example how you can make simple things unneccesary complicate.
and im a little angry about it, because i wasted way too much time in getting the
result i wanted.
