Power + volume down doesn’t invoke the full-screen shot. I expected it to, considering that (per https://www.reddit.com/r/pinephone/comments/17210bz/phosh_take_a_screenshit/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button) Phosh uses GNOME Shell’s underlying implementation to do so.
Spectacle isn’t installed by default, but would a default binding exist which can be invoked on a mobile device, and can one be set with these buttons (if not)?
