As I walk around meeting with our engineers, I notice they will frequently have dozens of files open in Understand’s GUI. They use the “Window Selector” to move quickly between them.
To launch the Selector choose “Window->Windows Navigator”, or use Ctrl-Tab or Ctrl-Shift-Tab. Ctrl-Tab automatically moves you to the next tabbed document of the same type (e.g. editor, graph). Ctrl-Shift-Tab moves you to the left next document of the same type.
Rather than explaining everything about it, I suggest you just try it.
But I will explain its two modes. The default mode is what I just showed you. Use Ctrl-Tab and Ctrl-Shift-Tab to move left and right in documents.
The second mode is very useful when you have lots of files and aren’t sure where the heck they are. Set it by checking the “Sticky” box.
This will keep the Navigator window open. Now you can type to filter the list of files and use the arrow keys to navigate through the filtered list. Here I typed “.h” to filter to all .h files:
I usually have that box checked. I can have the best of both worlds.
I can hit Ctrl-Tab, Ctrl-Tab, and so forth to navigate where I want. When I hit Enter – it loads the file. Or I can type a filter, use arrows and hit Enter to load. Either way, no mouse – which is a good thing.
Alternatively you can select View->Window Selector and always have a list of all opened tabs.
