G'day Gonzalo,
Thanks for the reminder. Yes, it matches somewhat with #11223 and
#11468, especially the mapping of the keys that Adam observes.
https://dev.laptop.org/ticket/11223
https://dev.laptop.org/ticket/11468
No fix is possible at the moment, but changing procedure works fine.
p.s. my posts are not getting through to devel@ or support-gang@ due
to the DNS damage affecting laptop.org.
