For example: you may want to have documents (with a .XL suffix) automatically open MS EXCEL and the file contents. This will require additions to the 'Helper Application...' settings.
1) Select 'Preferences...' from the 'Options' Menu
2) Click on the 'Helper Applications...' button
3) Click on the 'Add document type...' button
4) Enter 'application/excel' in the textbox.
If you are adding another application you can select an appropriate name after the '/'.
This is actually a MIME name and as such should follow specified(?) guidelines. I
believe one should use x-excel instead of excel but the excel entry works (for now).
Click 'OK'
5) Click on the 'Set Application...' button
6) Find the Application on your hard drive(s).
[You do have the application, don't you :-) and you know where it is!]. Click 'Open'
7) Pick a filetype. [Your guess is as good as
mine]. XLS seems to work for MS Excel on the Macintosh. Click 'OK'
8) Click 'OK' in the 'Changes will not take....'
dialog box. Go back to step 3 if you want to add more document types.
9) Next, click on the 'Add Extension...' button
10) Enter 'XL' in the text box and
select 'application/excel' [or application/x-excel] and click 'OK'
11) Go to step 9 if you wish to enter more
extensions (for example WORD for application/msword and XLS for application/excel).
Otherwise click 'OK'
12) Click the 'Apply' button
13) Quit from Mosaic by selecting 'Quit'
from the 'File' menu. The next time you use MacMosaic it should use the new
information you have just added.
