auto-indent in fortran mode: nedit vs xemacs

[Giuseppe Angilella]

Hi,

I'd like to move from xemacs to nedit.

One of the features of xemacs (seemingly) missing in nedit is, however, 
the possibility of auto-indenting a line by giving a tab character in the 
middle of a line.

I know I can set a new default setting for the Emulated tabs, which I did, 
setting the value to 6 spaces. This is helpful in shifting a line six 
characters to the right, by typing tab _at the beginning_ of the given 
line.

However, in xemacs, when typed _in the middle_ of a given line, a tab 
automatically shifts the whole line the necessary number of spaces to the 
right (e.g. 6, or 9, or 12), in order to indent it properly, e.g. when 
within a do or if loop.

Is there any way of customizing the behaviour of the tab character also in 
nedit, perhaps only within the Fortran mode?

Many thanks.

Giuseppe.
