Two boxing on a single machine

[ThadeusOfShibboleth]

I know there are threads about two boxing but I could not find one that had the info I need via the search option.  Here is my question...While running two instances of EQ2 on a single machine, is there a way (that doesn't violate the EULA) to send a single keystroke to both instances of the game at one time?  For instance, if I hit my 5 key it would register hotkey 5 on both instances of the game?I am NOT looking to exploit in any way shape or form, just to simplfy my two boxing by eliminating the need for alt-tab.Thank you.
