MACBENUTZER  BTW, 3 of these functions: all caps, all lowercase, and initial caps for words can all be done by creating a key bindings file. Learn how to do this, and there's a whole bunch of convenient things you can do.

Unfortunately, this method does not let you define functions that can see what the text it's changing contains, so it cannot replace most of the great functionality in WordService.

MACBENUTZER  I love this new functionality, but I wish it wouldn't limit the Smart Quotes command to a single language per user. I use my computer for both English and German, and even though Smart Quotes can handle either, it chooses the language based on a single key in the info.plist file, so you can't set it up to give you both a "Smart Quotes English" and a "Smart Quotes German" function.

Unless, of course, someone out there knows a way to do this.

MACBENUTZER  TextEdit is fine for taking notes that you'll use only in soft copy. When I used Windows, I used plain text files for notes. With TextEdit, I can use proportional type.

But I wouldn't use TextEdit for printing. The margins are enormous, and Apple will not let you change them. You can edit the RTF itself, but when you reduce the margins that way, good old Steve Jobs will just increase the font size so that the line breaks don't change, and you'll wind up wasting even more paper.

For printing, I now use Bean. It's free, open source, just as fast as TextEdit, and you can safely change the margins.

MACBENUTZER  I found your problem.

Yes, it's a step backward, but in Mac OS 10.4, "Services" is not a menu on the menu bar. It's in the application menu (e.g., "TextEdit") under the sub-menu for "Services". It's intermixed with all of the other services.

That makes it 1 step more work to use. So I would only use those that you can put on keys.

BTW, I also discovered that the key shortcuts are disabled for those keys that are already used by the application. To fix this, redefine the shortcut to a key available in all of the applications you use it with.
