Places the current selection on the Windows clipboard. If there is no current selection, and the option to copy the active line is turned on in the Editor Preferences, then the entire current paragraph is placed onto the clipboard.
If the clipboard holds text data, the selection is appended to the text already on the clipboard. Edit|Paste will then paste both the original text plus the selection appended to it.
If the file uses syntax coloring, and the clipboard already holds a rich text version of other text copied by EditPad, then the rich text version is appended to as well. If the clipboard holds rich text copied by another application, Edit|Copy Append removes it from the clipboard.
This command is always invoked on whichever editor is showing the text cursor (vertical blinking bar), regardless of whether you use the main menu, a toolbar button, or a keyboard shortcut.
