To use keyboard input, you need to click on the answer area to focus it. "KEYBOARD ON" will appear in the top right corner. The key mappings are as follows:
| Function | Key |
|---|---|
| C/AC | c / C |
| +/- | ~ |
| % | % |
| + | + / NUMPAD + |
| - | - / NUMPAD - |
| × | * / NUMPAD * |
| ÷ | / / NUMPAD / |
| = | Enter / NUMPAD Enter / = |
| 0~9 | 0~9 / NUMPAD 0~NUMPAD 9 |
| . | . / NUMPAD . |
Pressing the clear key once clears the current step, and pressing it again clears everything.
