If you have used Go|Back in Edited Files to go back to a previously edited file, then you can use the Forward in Edited Files command in the Go menu to move forward in the list of recently edited files.
Go|Forward in Edited Files does not have a submenu. The Go|Back in Edited Files submenu lists all recently edited files. If you have already gone back to a previously edited file then this file has a check mark in the submenu. Selecting a file above the one with the check mark moves you forward.
