198 Shortcuts for Entering Math Expressions
Shortcuts for Entering Math Expressions
Shortcuts let you enter elements of math expressions by typing instead of using the
Catalog or Symbol Palette. For example, to enter the expression √6, you can type sqrt
(6) on the entry line. When you press ·, the expression sqrt(6) is changed to
√6. Some shortcuts are useful from both the handheld and the computer keyboard.
