David,<div> </div><div>I had to use "attr.save-on-deactivate" in the Scope Selector instead, but that did the trick! Thanks so much for explaining this to me. <div class="gmail_quote">On Wed, Feb 29, 2012 at 12:39 PM, <<a href="mailto:textmate-request@lists.macromates.com">textmate-request@lists.macromates.com</a>> wrote:<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> ------------------------------ Message: 4 Date: Wed, 29 Feb 2012 18:39:20 +0000 From: David Howden <<a href="mailto:dhowden@gmail.com">dhowden@gmail.com</a>> To: TextMate users <<a href="mailto:textmate@lists.macromates.com">textmate@lists.macromates.com</a>> Subject: [TxMt] Re: textmate Digest, Vol 45, Issue 50 Message-ID: <CAP2kWKGbE+81=<a href="mailto:t_5On1x_hDbdXaZr9LOO7gTwWifCUnxk%2BNH-Q@mail.gmail.com">t_5On1x_hDbdXaZr9LOO7gTwWifCUnxk+NH-Q@mail.gmail.com</a>> Content-Type: text/plain; charset="iso-8859-1" Hi, So this works for me. In the .tm_properties file: [ *.tex ] scopeAttributes = 'attr.save-on-deactivate' Then put attr.save-on-deactive in the scope for the 'Save on focus lost' command. Be careful: scopeAttributes seem to only be attached to files when you open them, so if you change .tm_properties be sure to re-open the files. You can make sure that the scope attribute has been set by using the "Show Scope" command in bundle development or Ctrl-Shift-P, just to check that the attribute is being set properly.
