The application launches with onscreen instructions. Ongoing usage has a fullscreen text editor with a one-row menu bar along the bottom. The menu bar is accessed using the codice_1 key, and is navigated with the arrow keys and codice_2 key. The application operates in insert mode, so existing characters are edited only by deleting instead of typing directly over them. codice_3 from the right is used instead of codice_4 from the left. The application can help prevent the orphaning of a paragraph's line across a page break. There is a full-screen print menu. The application's namesake feature allows the user to begin a selection, use the arrow keys to mark the full selection, and end a selectionthen cut it and paste it. The clipboard buffer persists between different documents.
