\define focusEditorDescription() Simply focuses the Text Editor

A `tm-edit-text-operation` invokes one of the available operations on a __surrounding__ text editor. Therefore the message has to be dispatched within the editor in order for it to catch it. The following properties on the `event` object are required:

|!Name |!Description |
|param |Name of the operation to be executed, see ''below'' for a list of possible operations |
|//{any other params}// |Any other parameters are made available as variables within the context of the widget message. |

The `tm-edit-text-operation` message is usually generated by a ButtonWidget or an ActionWidget and is handled by the surrounding text editor.

! Text Operations

At this point the following text operations have been implemented:

|!Name |!Description |
|<<.def "excise">>|<<exciseDescription>> |
|<<.def "replace-all">>|<<replaceAllDescription>> |
|<<.def "replace-selection">>|<<replaceSelectionDescription>> |
|<<.def "prefix-lines">>|<<prefixLinesDescription>> |
|<<.def "wrap-lines">>|<<wrapLinesDescription>> |
|<<.def "wrap-selection">>|<<wrapSelectionDescription>> |
|<<.def "save-selection">>|<<saveSelectionDescription>> |
