Raspberry PI - Keyboard

[BenoitM]

For some reason the Raspberry key no longer works to type APL characters. It just opens the Raspberry menu. On Ride I can use the ` key, but on APL (TTY) nothing works.

Please help

Thank you

Hi BenoitM,

Please write to me at Dyalog Support and let me know what Raspberry Pi hardware you have, what version of Dyalog, and what operating system you are running on.

Regards,

Vince

Can you also describe how you set up APL input on your Raspberry Pi?

Prior to 18.2, APL input using the Windows key (Raspberry key) was enabled when starting Dyalog by default. This persists even after exiting Dyalog, which was confusing for many users, so we disabled it. From 18.2 onwards, you need to use

Code: Select all

dyalog -kbd

.
For more options, you can choose the APL shifting key on non-Wayland desktop environments using the setxkbmap command.

Code: Select all

setxkbmap -layout us,apl -variant ,dyalog -option grp:switch

The grp:switch part means that APL symbols are available while the Right Alt key is pressed. The Raspberry key will be the "win" key

Code: Select all

grp:win_switch

.
The full list of available shifting keys can be found with

Code: Select all

cat /usr/share/X11/xkb/rules/evdev.lst | grep grp
