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.
