Shortcut: Alt+C
Column mode changes the operation of the editor for selecting text. When selecting in column mode, the selection is set based on the character column position of the first character selected to the column of the last character of text selected. Text selected in this mode does not automatically include all text between the start and end position, but includes all text in the columns between the first and last character selected.
Column mode editing is sometimes referred to as "block mode editing," as selecting text in columns forms a rectangle.
Cut, copy and paste work with a column of selected text as they do with a normal selection. However, when a column of at least one or more character is selected, typing will not overwrite the selection (as is expected with normal editing). Instead, typing a character will fill all selected columns with that character.
You can make "quick" columnar selections by holding the Alt key and left-clicking and dragging the mouse. Word wrap must be disabled for this to work.
Column mode editing requires that word wrap be turned off. Additionally, a fixed pitch font must be used for column mode, set by the Set hex/column font command in the View tab.
There are several other column-related commands that are only available when column mode is active, such as Insert/fill columns, Delete columns, Cut columns and Insert number.
