Enter Extended Characters:

When entering text, Lotus Notes allows you to enter what is called "extended characters". There are things like accented characters (â, ä, á, å), symbols (®, ™, ©), fractions (½, ¼, ¾), and more. There are two ways to enter these extended characters.

The first is to press ALT+F1, then press the appropriate "Compose sequence". For example:
™ is created by pressing ALT+F1, then t, then m.
® is created by pressed ALT+F1, then r, then o.
Note: The "compose sequences" are different for Windows and Macintosh.
The second way to create extended characters is a little more complex, but is consistent across Windows and Macintosh. You can press ALT+F1, then ALT+F1 again, then the appropriate "Extended compose sequence". For example:
® is created by pressing ALT+F1, then ALT+F1, then 0-169.
© is created by pressing ALT+F1, then ALT+F1, then 0-184.
For your reference, the list of extended characters available is easily found in your Lotus Notes Help database in the document "Special characters listed by extended compose sequence". Alternatively, you can access the list on web via Special characters listed alphabetically by name of character , or Special characters listed by extended compose sequence.
