Answer 1

1. Install the xautomation package (sudo apt-get install xautomation). This provides the command xte which is used for simulating keyboard events.
2. Open up System ➜ Preferences ➜ Keyboard Shortcuts.

3. Click on Add and use the following code for the Command,

   xte "keydown Control_L" "key s" "keyup Control_L" "keydown Alt_L" "key Tab" "keyup Alt_L" "key F5"
   

   Use whatever you want for the Name and then click Apply.

   

4. Now click the right side of the new shortcut entry (where it says Disabled ) and hit

   Alt+Shift+S.
