 	  instead of "show", for consistency. (DLR)
 	- In the main shortcut list, move the "Refresh" shortcut down to
 	  after the "Enter" shortcut, for consistency. (DLR)
+	- Add the ability to go to the first and last line of the
+	  current file from the main list via Meta-/ and Meta-\.  Also,
+	  make sure all the equivalent shortcuts in the search, replace,
+	  and "Go To Line" lists accept both the meta keys and the
+	  equivalent function keys. (DLR)

+- help.c:

+	- Call get_shortcut() after getting input, so that we only have

 - nano.c:
   renumber()
 	- Remove invalid assert. (DLR, found by Filipe Moreira)
