Ability to let users use WIN + Key shortcuts

[a-camacho]

Is your feature request related to a problem? Please describe. When doing exams, some students are able to move a window bellow SEB bottom bar. When that happens it is quite impossible to move again this window.

Describe the solution you'd like Windows have shortcuts to move windows on screen (WIN + up/down/left/right). It would be great if Safe Exam Browser would allow those shortcuts.

Describe alternatives you've considered A button - somewhere - that triggers a "maximize" of all windows ? But better would be to allow the shortcuts.
