Hi JD,
Yes, if you change the selection mode to "append" (in the main menu:   
Select... Selection Mode... append).

Then in the Sequence panel, each segment you drag out adds to the  
existing selection, so eventually you can have multiple segments  
selected.  The highlighting in sequence blinks off while you are  
dragging a new segment, but when you let up, they will all be selected.

You probably want to turn the selection mode back to the default  
"replace" afterward to avoid confusion.

As a command-line person, I'd probably instead just mouse over the  
sequence to find out the sequence numbers and then use the numbers in  
various commands (which could include selecting them: select : 

However, there are many different ways to accomplish the same result  
in Chimera, so use the one that you like!
I hope this helps,
