Keyboard shortcuts need documentation or implementation
Currently the Tails OS has implemented a few shotcuts for its users and documented it here: https://tails.boum.org/doc/first_steps/accessibility/index.en.html#index2h1
But the list of shortcuts is meant to be an assistive feature. The OS lacks commonly used shortcuts or at least the documentation for such as cut, copy, paste, undo, redo, switch between applications, select all. etc. According to our study on usability of Tails in India , several participants expressed missing the usage of these shortcuts in Tails OS. These shortcuts have to be implemented and documented similar to this gnome documentation a better user experience (https://help.gnome.org/users/gnome-help/stable/shell-keyboard-shortcuts.html.en)
