QA:Testcase desktop common shortcuts

Description

This test case tests whether commonly-used, de facto standard keyboard shortcuts work in a given desktop environment.

Setup

1. Boot into the distribution release and desktop you wish to test
2. Take into account any changes you have made to the default keyboard shortcut configuration

How to test

1. Try these common keyboard shortcuts:
   • F1 (from within an application that is part of the desktop being tested)
   • Alt-F2
   • Alt-F4 (from within an application, which it is safe to quit)
   • Alt-Tab
   • 'Super' key (also called 'Windows key')
   • Ctrl-Alt-up
   • Ctrl-Alt-down
   • Volume up (if available)
   • Volume down (if available)
   • Mute (if available)

Expected Results

1. F1 from within an application should launch the help system
2. Alt-F2 should bring up the desktop's 'run application' dialog
3. Alt-F4 should close the active window (usually, quitting the application)
4. Alt-Tab should bring up a window switcher display, and with each successive press, switch to a different window
5. The 'Super' (Windows) key should initiate the desktop's menu system or overview
6. Ctrl-Alt-up should switch up to the current workspace (if you have multiple workspaces)
7. Ctrl-Alt-down should switch down to the workspace (if you have multiple workspaces)
8. The volume up key should increase the system volume
9. The volume down key should decrease the system volume
10. The mute key should mute system audio
