-The QGIS Python Console is an interactive shell for the python command executions. 
-It also has a python file editor that allows you to edit and save your python scripts. 
-Both console and editor are based on PyQScintilla2 package.<br>
-The console is split in two main panes, top and bottom one 
-resizable by using the horizontal splitter. Output area pane is a widget read-only which 
-shows the commands output. You can drag and drop or copy and paste text into input area and 
-execute code snippets from the output pane by selecting some text and clicking on the 
-<label>Enter selected</label> command from the context menu. 
-No matter if selected text contains the interpreter prompt (>>>, ...). Input area pane is the interactive 
-python shell for input commands.<br>To access to the python file editor use the 
-<label>Show editor</label> button 
-from the toolbar. The editor allows editing and saving python files and it offers basic functionality 
-for managing your code (comment and 
-uncomment code, check syntax, share the code via codepad.org and much more).

-<h3>Coordinate Reference System Selector</h3>
-
-<p>
-  The Coordinate Reference System Selector allows you to set the projection for
-  the current layer.
-</p>
-<p>
-  You can find a coordinate system by entering its name, EPSG code or the QGIS ID
-  into the <label>Filter</label> text field. The list of recently used
-  coordinate systems are available at the top for quick access.
-</p>
-<p>
-  When operating across layers, for example, computing intersections between
-  two layers, it is important that both layers have the same CRS. To change the
-  projection of an existing layer, it is insufficient to simply change the CRS
-  in that layer's properties. Instead you must save the layer as a new layer,
-  and choose the desired CRS for the new layer.
