Shortcuts let you enter elements of maths expressions by typing instead of using the Catalogue 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.
