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 shortrcuts are useful from both the handheld and the computer keyboard. Others are useful primarily from the computer keyboard.
