KeyMapper not working

Hi, Raspberry Pi newbie here, dived straight in trying to get a BeebIt working on RISC OS, I’m using a Logitech K400R wireless keyboard which has no BREAK key, so I can’t boot any disk images with SHIFT-BREAK.

Found and downloaded KeyMapper (to map another key to BREAK), and a web site with the keyboard codes.

If I double-click the KeyMapper module then press F12 and type keymap I can map keys, e.g. keymap 85 86 should change all “N” key presses to “L”, but nothing happens, all “N” key presses are still displayed as “N”.

If I type keymap it reports
85 —> 86
so appears to be running… just not doing anything.

Anyone know how to get this working?

Keymapper uses “Low Level Internal Key Numbers” which you can get from here

85→86 would appear to map comma to full-stop rather than L-N which may be why you’re not seeing what you expect.

Thankyou that works! I had the wrong key codes :)
