I just spent about an hour searching the internet trying to figure out the keyboard shortcut to tab (or move) between the split windows within a tab in Coda 2. After looking through the Apple shortcuts, I finally found one that works:
Control + Tab
It’s so simple. But there’s a catch. To get this to work you first must open another tab before opening the Terminal window.
Steps:
1. Create a new tab/document
2. Add a new split Document or Preview window
3. Add a new split Terminal window
4. Close the second Document or Preview
At this point you should be able to Control + Tab between the Document window and the Terminal window. It’s not ideal, but it works when needed.
On a related note, I’m interested to see what Panic has up their sleeve for Coda 2.5. It should be released soon.
