The calculator functions are listed below along with the hot key that calls the function and a brief description of the action. Each action except the speak keys can be performed by tabbing through the calculator to the item of interest and pressing the SPACE key. Pressing F1 when the focus is on an item will display an individual help file with detailed information about that item. When a hot key requires a capital letter, the key is noted with SHIFT.
The Hot keys are listed in five groups:
1. Numbers and operators
2. Functions called by SHIFTed letters
3. Mode controls
4. Memory and Display functions
5. Boolean Logic
Numbers: 0 1 2 3 4 5 6 7 8 9 0 a b c d e f
[Note that only 1 and 0 are valid numbers when the base is binary, 0-7 in
octal base, 0-9 in decimal base, and 0-f when the base is hex.
The hex numbers a - f are lower case]
Arithmetic operators: + (plus), - (minus or dash), * (multiply), / (divide or slash), = (equals), . (decimal, period, or full stop)
The () (left and right parentheses) are used to group numbers during a calculation.
Trigonometric functions replace the number in the display with the appropriate function value. The argument can be in units of radians, degrees, or gradients.
