Displays the following dialog:
The "Tabulator size:" field allows to specify the number of
columns to use for resolving tabulator characters in editor documents.
If "Store tabulator characters" is checked, tabulator characters
will be used on saving files to replace chains of space characters. The
"File format:" choice selects the end of line character for different
platforms. If "Platform" is selected, the environment will select
the end of line character for you. The file format settings will be stored
in the current project file.
