Hi. new to macs. It's going ok so far. How do I switch between windows in the same app using the keyboard? For example, multiple finder windows or multiple firefox windows. I know you apple-tab between applications. Speaking of multiple finder windows, if I've got a folder in my documents folder called "Spreadsheets" and one on my memory stick called "Spreadsheets" is there any way of telling which is which when they're both open in different finder windows? Thanks.
