Unreal Engine 4.x Scripting with C++ Cookbook - Second Edition

How to do it...

1. Hold down the Ctrl key while clicking to select an entire word:

2. Hold down the Alt key to select a box of text (Alt + left-click + drag):

You can then either cut, copy, or overwrite the box-shaped text area; in the latter case, the characters you type will be repeated in all selected rows.
