text_item->selected

text_item ->selected_completion: item=char_array, apply=[bool]

Called from @completer, a global browser object used to to display completions on a text_item or alternatives from the drop-down browser of a text_item.

@completer calls this method with a single argument representing the selected text.

This method appends the argument value to the prefix resulting from text_item<-split_completion, sets the text_item<-value of the text_item and hides @completer.
