There are situations where there is a need to make repetitive but identical changes to each line, or copy a block of text and then add the same text or spacing to each line when editing source code. Column editing allows a way to enter or delete text on multiple rows at once.
Access this feature by pressing the CTRL key while making a selection with the left mouse button. This enables selecting a rectangular region to be able to type to replace its contents, paste over it, or delete it.
The following are some examples.
1. Editing identical variable types
In the above illustration, column select the "int" type, and then simply type "unsigned int", to all 3 lines at once.
2. Working with Enums
Above shows a selected rectangle consisting of all of the enum variants to avoid copying the spacing. Pasting it into the switch statement maintains its tabbing. Next insert "case" into each line by simply column select the space before "SHAPE" and type "case".
