This might help too. I use the top number row to attack, the arrow keys to move and the mouse to click things. So I added this macro to my WS:
/macro SQ "powexectoggleon dark nova$$goto_tray 7" then I copied the powers down to tray 7. And of course, for the dwarf:
/macro LB "powexectoggleon black dwarf$$goto_tray 8" then copied those powers to tray 8.
Unfortunately, there is no "human" form to turn on, you turn off the other forms.
So I stole this from above: /macro HM "powexec_toggleoff Black Dwarf$$powexec_toggleoff Dark Nova$$goto_tray 3"
I also added to trays 7 & 8 a "human" macro. /macro HM "powexectoggleoff dark nova$$goto_tray 3" and of course /macro HM "powexectoggleoff black dwarf$$goto_tray 3"
Also, I have "FLY and land" macros. /macro FLY "powexectoggleon dark nova$$autorun 1$$goto_tray 7" and /macro land "powexectoggleoff dark nova$$autorun 0$$goto_tray 3"
Switching to the nova tray is a good idea if you get attacked while flying.
I also stole the tab key bind from above.
SQ = squid, LB = lobster, HM = human
