Beginning and ending session Markers

[braddh]

Hi, I'm a recent ProTools (Mbox 6.4 LE) user and am still in that learning curve phase. When recording a session sometimes I'll have 10-15 seconds of click track or dead space before my first instrument is played. How do I move the session marker up to that first guitar strum or note. Rather than dragging each wave file back to the original 0:00 point. I've scoured the Mbox manual and my "ProTools for Dummies" book and can't seem to locate this action. Every time I think I've found the answer in the books, and perform the keystrokes, my session marker jumps back to the original 0:00. I'm sure it's probably something stupidly easy. Thanks.....

I always use 'Cut Time' from the Midi drop down menu...just select/highlight the space you want to cut and select Midi then Cut time. I am sure there are other ways to do this also.
