The documentation here How to copy and paste text | Qubes OS suggests that the incantation would be:
qvm-features dom0 gui-default-secure-copy-sequence 'Mod4-Shift-c'
qvm-features dom0 gui-default-secure-paste-sequence 'Mod4-Shift-v'
but that didn’t work. And likewise apeing the format in the global settings GUI:
qvm-features dom0 gui-default-secure-copy-sequence 'Win+Shift+C'
qvm-features dom0 gui-default-secure-paste-sequence 'Win+Shift+V'
is also a no-go. So what’s the incantation I need? And how can I find documentation about this kind of thing in general? man qvm-features
is kinda useless and I can’t seem to find a way to get qvm-features
to actually print anything about the current configuration of the system.
