 to remember are the following:

+* :kbd:`Shift-Enter`:  run cell
     Execute the current cell, show output (if any), and jump to the next cell 
     below. If :kbd:`Shift-Enter` is invoked on the last input cell, a new code 
     cell will also be created. Note that in the notebook, typing :kbd:`Enter` 
     on its own *never* forces execution, but rather just inserts a new line in 
-    the current input cell. In the Notebook it is thus always necessary to use 
-    :kbd:`Shift-Enter` to execute the cell (or use the ``Cell | Run`` menu 
-    item).
+    the current input cell. :kbd:`Shift-Enter` is equivalent to clicking the 
+    ``Cell | Run`` menu item.
 
-* :kbd:`Ctrl-Enter`: 
+* :kbd:`Ctrl-Enter`: run cell in-place
     Execute the current cell as if it were in "terminal mode", where any 
-    output is shown, but the cursor *remains* in the current cell. This is 
-    convenient for doing quick experiments in place, or for querying things 
-    like filesystem content, without needing to create additional cells that 
-    you may not want to be saved in the notebook.

-* :kbd:`Alt-Enter`: 
+    output is shown, but the cursor *remains* in the current cell. The cell's
+    entire contents are selected after execution, so you can just start typing
+    and only the new input will be in the cell. This is convenient for doing
+    quick experiments in place, or for querying things like filesystem
+    content, without needing to create additional cells that you may not want

+* :kbd:`Alt-Enter`: run cell, insert below
     Executes the current cell, shows the output, and inserts a *new* input 
-    cell between the current cell and the adjacent cell (if one exists). This  
+    cell between the current cell and the cell below (if one exists). This  
     is thus a shortcut for the sequence :kbd:`Shift-Enter`, :kbd:`Ctrl-m a`.
