ff-switch-file
ff-switch-file is a compiled Lisp function in `find-file.el
'.
(ff-switch-file F1 F2 FILE &optional IN-OTHER-WINDOW NEW-FILE)
Call F1 or F2 on FILE, according to IN-OTHER-WINDOW.
In addition, this runs various hooks.
Either F1 or F2 receives FILE as the sole argument.
The decision of which one to call is based on IN-OTHER-WINDOW
and on the global variable `ff-always-in-other-window'.
F1 and F2 are typically `find-file' / `find-file-other-window'
or `switch-to-buffer' / `switch-to-buffer-other-window' function pairs.
If optional NEW-FILE is t, then a special hook (`ff-file-created-hook') is
called before `ff-post-load-hook'.
