Hotkey for switching between tabs / window panes on a Mac

I'm not clear on your specific question. Here are a couple of shortcuts that may be helpful.

• Command + Tab = switch between applications
• Command + ~ = switch between windows of an application
• CTRL + Tab = move forward through tabs (in same window)
• CTRL + Shift + Tab = move backward through tabs (in same window)

My personal favorite is to hold Command + Shift and then use [ to flip left through tabs and ] to flip right.

I finally found the answer. You have to hit Command + [number of desired tab]. e.g. Command+1 takes you to the first 'tab', Command+2 the second, etc etc.
