I don't seem to recall such a shortcut, but you can create one by adding
an entry to a private version of  To do this, you
will need to do the following.

1) Determine the location of the private file by evaluating this
expression in a notebook.

      {$PreferencesDirectory, "SystemFiles", "FrontEnd", "TextResources"}
]; LinkRead[$ParentLink]

This will return a string containing the full path.

2) Create a directory with the path shown in step (1).

3) Determine the location of the shared version of this file by evaluating
this expression in a notebook:

      {$TopDirectory, "SystemFiles", "FrontEnd", "TextResources"}
]; LinkRead[$ParentLink]

Again, this will return a string with the full path.

4) Copy from the directory you found in step
(3) into the directory you created in step (1).

5) Open the newly copied file in your favorite text editing program.

6) Note that there is a large Mathematica expression in this file that has
the head EventTranslations.  The expression contains a list of
subexpressions with head Item.  All you need to do is add an item that
perform the action you want.

Suppose, for example, that you wanted to define Ctrl-u to be the shortcut
for extending the selection the complete cell.  You could add something
like this:

  KeyEvent["u", Modifiers -> {Control}],
  FrontEndExecute[{SelectionMove[InputNotebook[], All, Cell]}]

Note that you should exercise caution in adding key translations so that
they do not conflict with existing shortcuts.
