The Notes App lists the files of /notes by their first line, newest first: n starts a note, Enter opens it, r renames its file, d deletes it after asking, s sorts by name. A new note's file is named after its first line. The editor wraps at spaces, 38 columns by 8 rows; Fn+arrows move through the wrapped text, Ctrl+A and Ctrl+E go to the ends of the line. There is no save key: the note is written five seconds after the last key, on Back, on leaving the App, when the screen turns off and before the device powers off. A save writes a temporary file and puts it in the note's place; a save cut short is put back, or offered, the next time. A note is up to 16 KB, held in one buffer reserved when it's opened: the file is read straight into it and typing never makes it grow. A failed allocation aborts on this device, and with IRC connected the largest free block is about 31 KB: a first version that copied the note once on loading restarted the device when a full note was opened with IRC connected. Editing files of any size is #47. The Storage App's text viewer gets `e`, which edits a text file up to 16 KB with the same editor unless the file is read-only. 439 host tests. Checked on the device: docs/milestones/F1.md. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EhqxQ49eCju4CzKYNjZzwT
