This also acts as a general-purpose "deselect" shortcut since pressing it a second time will deselect text. This is available both in the script editor and in TextEdit fields in use, both in the editor and projects. The Duplicate Line script editor shortcut was moved to Ctrl + Shift + D since it conflicts with the new shortcut (Ctrl + D). The rationale for doing so is that Duplicate Line is a less commonly used action, and its behavior can be replicated by copying and pasting the current line anyway. (With no selection active, the whole line will be copied.)
