On my machine, it swapped back to the previous one I had used from five open designs in a single window, then it stepped to one I had not been to, then through them, back to the original, then the sequence again.
So with tabs in order 1 to 5 and starting on tab 2, I then selected tab 5. On using Ctrl-Tab, it focused back on tab 2, then tab 4,3,1 and then 5 to 2 and so on around.
Well, the "most recently used tab switching" in your case would behave as follows:
quote:With tabs in order 1 to 5 and starting on tab 2, I then selected tab 5.
On pressing and releasing Ctrl-Tab it focuses on tab 2. On another pressing and releasing Ctrl-Tab it focuses on tab 5. On another pressing and releasing Ctrl-Tab it focuses on tab 2. And so forth it switches between the same two tabs.
But on pressing and holding Ctrl and while it's held pressing and releasing Tab it cycles through all tabs (in most resent order).
The whole idea is to be able to switch back and forth between two tabs (current and most recent) while more than two tabs are opened.
For example this is the behavior of Alt-Tab in Windows (switching between opened windows).
Usecases are obvious: - Working with two schematic sheets that are related to each other (e.g. PCIe connector and PCIe switch) - Working with layout and a schematic sheet from which components are currently being placed
