There are a few keyboard shortcuts that sometimes get activated by mistake when a student takes an exam in high-security mode.

The keyboard shortcuts are shown below:

• CTRL+SHIFT+SPACE (Changes keyboard language.)
  
  
• CTRL+PLUS (Zooms in.)
  
  
• CTRL+MINUS (Zooms out.)
  
  
• CTRL+SEARCH+D (Shows a zoomed mode on the upper half of the screen.)
  
  
• CTRL+SEARCH+M (Enlarges the full screen.)
  
  
• CTRL+SEARCH+H (Inverts all colors.)
  
  
• CTRL+ALT+Z (Chromevox. May show an orange box around the text.)
  
  
• SEARCH+PERIOD (.) (Overwrites, i.e. replaces text instead of inserting it.)
