ses: Resizing

 
 3.2 Resizing the spreadsheet
 ============================
 
 Basic commands:
 
 ‘C-o’
      (‘ses-insert-row’)
 
 ‘M-o’
      (‘ses-insert-column’)
 
 ‘C-k’
      (‘ses-delete-row’)
 
 ‘M-k’
      (‘ses-delete-column’)
 
 ‘w’
      (‘ses-set-column-width’)
 
 ‘TAB’
      Moves point to the next rightward cell, or inserts a new column if
      already at last cell on line, or inserts a new row if at endline
      (‘ses-forward-or-insert’).
 
 ‘C-j’
      Linefeed inserts below the current row and moves to column A
      (‘ses-append-row-jump-first-column’).
 
    Resizing the spreadsheet (unless you’re just changing a column width)
 relocates all the cell-references in formulas so they still refer to the
 same cells.  If a formula mentioned B1 and you insert a new first row,
 the formula will now mention B2.
 
    If you delete a cell that a formula refers to, the cell-symbol is
 deleted from the formula, so ‘(+ A1 B1 C1)’ after deleting the third
 column becomes ‘(+ A1 B1)’.  In case this is not what you wanted:
 
 ‘C-_’
 ‘C-x u’
      Undo previous action (‘(undo)’).
