Re: Help me unlock a file while in emacs on the Mac

["Susan G. Conger" <congers@yoeric.com>]

Andrew,

Thank you so much.  I have a couple of question.  I put these in my 
.emacs file and they work except for one small problem.  The file is 
really unlocked but the buffer thinks that it is still locked.  I tried 
doing a C-X C-F to reread the file but it still thought it was locked.  
How would I change the mac-unlock-file so that it realizes that it can 
now edit the buffer and be able to save the changes back to the file.  
Also, I tried to assign F7 to the mac-unlock-current-file, however I 
could not figure out how to get it to except just F7 as the command key.  
Here is the commands that I tried:

(global-set-key "^[[18~" 'mac-unlock-current-file)
(global-set-key "f7" 'mac-unlock-current-file)

Thanks again,
Susan
