To insert a constant:

1.Position your cursor where you want the constant inserted.

2.Press to display the physics constants menu.

3.Press ÕÖ×Ø(or, you can press to access the next page, one page at a time) to scroll through the menu until the constant you want is underlined, then press to insert the constant.

Note that constants should be referred to by their names rather than their values, when used in expressions, equations, and programs.
