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 |
| +/- | ~ (shift+`) |
| % | % (shift+5) |
| + | + / NUM+ |
| - | - / NUM- |
| × | * (shift+8) / NUM* |
| ÷ | / / NUM/ |
| = | Enter / NUM Enter / = |
| 0~9 | 0~9 / NUM0~NUM9 |
| . | . / NUM. |
Pressing the clear key once clears the current step, and pressing it again clears everything.
