EM_SETSEL is used for "selecting" ranges of text.
0, -1 will select all.
-1, -1 will (I think) remove the selection.

Net result being that the cursor is moved to the end.

35 stands for the "end" key, so every keypress places the
cursor at the end of the text.



Basically they both do that exact same thing, just a different
way.

I know what your looking for, gimme a couple of days and I am
sure I can come up with something...
