@ -165,20 +165,12 @@ The value of the latest keypress on a hex keypad is stored at `$1B`.
The keypad uses the same layout as the COSMAC VIP (and CHIP-8). The CPU simulator maps those keys onto a Qwerty set:
```
1 2 3 C 1 2 3 4
4 5 6 D Q W E R
7 8 9 E A S D F
A 0 B F Z X C V
hex pad simulator
```
`1` `2` `3` `C`   =   `1` `2` `3` `4`
`4` `5` `6` `D`   =   `Q` `W` `E` `R`
`7` `8` `9` `E`   =   `A` `S` `D` `F`
`A` `0` `B` `F`   =   `Z` `X` `C` `V`
The arrow keys are also mapped onto the hex keypad:
```

7 8 9 ← ↓ →

```
` ` `5` ` `   =   ` ` `↑` ` `
`7` `8` `9`   =   `←` `↓` `→`
