SendKeys From Excel

I'm trying to send information to another application using the SendKeys function but it isn't working. The primary code that I'm using is:

ActiveWorkbook.FollowHyperlink Address:="http://www.aasb.com.au/public_docs/aasb_standards_2005/compilations/AASB101_07-04_COMP_11-05.pdf", _
NewWindow:=True
AppActivate "Microsoft Internet Explorer"
Application.SendKeys "^F34.~", True.

Sometimes I get an error on the AppActivate statement and sometimes the SendKeys function works but not all the time. Does anyone have any suggestions about what I'm doing wrong for it to not work all the time?
