How to send multiple Keystrokes?

Hello,
I want to open a new TAB in Firefox an afterwards to jump to my Startpage. This would be: CTRL + T and CTRL + H.
I've tried everything, but nothing worked ;-(
If I would post all my tries, this thread would be very long ;-)
As far as I know there is a problem, that "Send Keystrokes" sends those Keycommands at the same time, and not afterwards.

Any Ideas for a workaround?

P.S: StrokeIt is the best program ever!!! Friends are asking me, how I can work with Window so quick! They only see blue lines. I DO everything with StrokeIt, even with IRC! ;-) e.g. yes, no, bye, hello, lol, ;-), ;-(, etc...
I could not live without StrokeIt!

[CTRL_DOWN]t[CTRL_UP]
[ALT_DOWN][HOME][ALT_UP]

sorry for the inconvenience
