fortran-indent-subprogram).
Fortran mode redefines TAB to reindent the current line for
Fortran (fortran-indent-line). This command indents Line numbers
and continuation markers to their required columns, and independently
indents the body of the statement based on its nesting in the program.
The key LFD runs the command fortran-indent-new-line,
which reindents the current line then makes and indents a new line.
This command is useful to reindent the closing statement of `do'
loops and other blocks before starting a new line.
The key C-M-q runs fortran-indent-subprogram, a command
to reindent all the lines of the Fortran subprogram (function or
subroutine) containing point.
The key M-LFD runs fortran-split-line, which splits
a line in the appropriate fashion for Fortran. In a non-comment line,
the second half becomes a continuation line and is indented
accordingly. In a comment line, both halves become separate comment
lines.
