Switch through files(Tabs) in the Editor

1. Call up the list of all open tabs in the Editor by by pressing Ctrl-Tab while keeping the ctrl key pressed.
2. Still with the ctrl key pressed, browse through the list of open tabs by hitting Ctrl-Tab; browse backwards through the list with Shift-Ctrl-Tab. Releasing the keys switches to the selected tab.
3. Pressing Ctrl-Tab once and then letting both keys go immediately, will switch directly back to the previous tab used.

Note however, that in some operating systems, Ctrl-Tab is already associated with another conflicting action. In this case, use Ctrl-~ instead.
