That is fine. I was surprised why (setq ess-sas-local-unix-keys t) does
not work.

I do not use BUGS so I do not think ess-revert-wisely will help. After
some testruns, I find that it is pretty tricky to mix batch and
interactive mode. F3, F4, etc only work for batch mode and C-c C-r etc
only work for interactive mode.

The idea ways (to me) to use ESS/SAS mode would be:

In batch mode:

1. open emacs
2. F3, run, F4 go back to program window etc. 
  Problem: with ess-sas-local-unix-keys, I can not
  use F4 to go from sh or log window to the program window.
  This only works for ess-sas-global-unix-keys.

In interactive mode:

1. open emacs
2. M-x SAS
3. Since ESS know that I am in interactive mode, I would like to use
  F3 to submit the buffer, F4, F5, F6 switch between program, SAS.lst, 
  SAS.log window. 
  Problems: 
    a) No easy way to switch between windows. (F3, F4 will cause
       confusion now.)
    b) Log and lst window do not automatically go to the 
       beginning of the newest log/output.
    c) Key bindings for ess-mode-map does not work for sas-mode. 
       I have to use sas-mode-local-map instead.

Mixture of batch and interactive mode: Very confusing.


In general, I would like to customize ESS/SAS with:

1. set ess-sas-global-unix-keys when I open a SAS file. I could
   not find a sas-mode-hook to do this.

2. In batch mode, map F4, F5, F6 keys for shell, output and list window
   so that I can switch between windows easily. (This is less intrusive
   than ess-sas-global-unix-keys.)

3. In interactive mode, map F4, F5, F6 to switch between SAS.lst,
   SAS.log and the program window.


Since I am new to ESS/SAS, my wishes might not be appropriate. Any
suggestion is welcome.
