4.4.1 Columns

Columns are split into a number of areas:

Column name
Each column has a name. You can pick any name you like when you make a new column with File / New / Column. There's no way to rename a column, unfortunately. Objects in the column are named using the column name, plus a number.

Column title bar
Drag with the left mouse button held down on the column title bar to move the column around the workspace. Double-left-click on the title bar to change the comment attached to the column. Hold down the right mouse button on the column title bar to pop up a useful menu.

The items in the menu let you edit the caption, select all the objects in the column, make a new column which is a copy of this column, save the column to a file, convert the column into a menu item (see §4.4.6) and remove the whole column.

Column Fold button
Left-clicking on the fold button folds the column away. Use this to hide columns which you still need, but which you are not interested in just now.

Expression entry
You can perform calculations by typing expressions directly into this box. For example, try entering the following expressions, and pressing Return:

                                                      
  2 + 2              
  A1 + 120              
  "My cat likes$\backslash$nlasagne"
