assign a second key long press?

[Duster78]

are there any hack that would allow me to assign a second long-press key in start>settings>buttons so that i can have one set for screen rotate and one to launch voice command? maybe the D-pad cener button for instance, i only have the option to set the send key for a long press command. i'm using DHarvey's rom and i love it, but since i like texting in landscape i cant figure out a way to launch voice command. any ideas? Thanks
