Eclipse has an MDI structure (Multi Document Interface), so the search panel, the package explorer and the code editor can all be open in one window, but I haven\'t found a keyb
And if you want to switch between perspectives its: Crtl + F8
and Ctrl + Shift + F8
. You can go to Help > Key Assist... for a full list of shortcuts (this list will change depending on the active editor etc.).
There are two ways to do it.
One is how @VonC did it, in an earlier reply; using CTRL+SHIFT+E which opens a box containing all the panes with their paths.
The other one is to simply use CTRL+E, which will open a pop-up just over your cursor containing the list of panes open. Parse using arrows and ENTER
If I understand your question correct, you are probably looking for Ctrl + F7 and Ctrl + Shift + F7. Other navigational shortcuts can be found in the menu: Window > Navigation.
Not an universal shortcut for going to any panel, but:
Ctrl+Shift+E
allows you to go back to any Editor (although it's still a little heavyweight for quick editor navigation).
