You may resize the rectangular text input area by selecting and dragging its lower right corner.
Two or more words separated only by hyphens (-) and/or forward slashes (/) with no space characters between them as in two-thirds, and/or, and right-to-life are counted as one word, which is the same way Microsoft Word and LibreOffice Writer count words.
You may type or paste text in the text input area, edit the text in the text input area, and select all the text in the text input area and copy or cut it to the clipboard memory and paste it elsewhere.
To delete all the text in the text input area, select all the text and press the BACKSPACE or DELETE key, or cut it to the clipboard memory.
