[PS/2 Spectrum keys](/til/spectrum/ps2-spectrum-keys "Permanent Link: PS/2 Spectrum keys")

If I’ve got a PS/2 connect to my spectrum then certain keys or buttons - like the NMI button - are mapped to either F-keys or key combinations.

This isn’t a complete list, but useful (to me).

| Function | Key | | --------- | --------- | | NMI | F9 | | Edit | Shift + 1 | | Caps lock | Shift + 2 | | Backspace | Shift + 0 | | Break | Space |

Keys that are required when in some other mode that I don’t know the name for (i.e. running .uart):

| Function | Key | | -------- | -------- | | Quote " | Ctrl + p | | Plus + | Ctrl + k | | Comma , | Ctrl + n | | Period . | Ctrl + m | | Colon : | Ctrl + z |

There’s also [this document](https://www.specnext.com/new-ps2-us-keymap/) that shows PS2 mappings to the spectrum, useful when you’re forced to use the "48K style keys".
