This is an interactive console, similar to Python's own command line interpreter.  Since it is embedded in Blender, it has access to all Blender Python modules.

Those completely new to Python are recommended to check the link button above
that points to its official homepage, with news, downloads and documentation.

Usage:<br>
  Type your code and hit "Enter" to get it executed.<br>
  - Right mouse click: Console Menu (Save output, etc);<br>
  - Mousewheel: Scroll text
  - Arrow keys: command history and cursor;<br>
  - Shift + Backspace: Backspace whole word;<br>
  - Shift + Arrow keys: jump words;<br>
  - Ctrl + (+/- or mousewheel): Zoom text size;<br>
  - Ctrl + Enter: auto compleate based on variable names and modules loaded -- multiple choices popup a menu;<br>
  - Shift + Enter: multiline functions -- delays executing code until only Enter is pressed.
