Instructions for okayedit:

Left-click a page at the top to switch to that page in the main (lower-left) pane and scroll it to where you clicked.
To play the song from the beginning, click PLAY ALL. To play it from a selected point, click PLAY AT or press P, then click the main pane where you want to start.
To stop the song, click STOP or press S.
To preview a note, click its instrument or press a key from 1-9 or A-F to select it, then right-click the main pane.
To place a note, left-click the main pane while a note is selected. You have a limited supply of edits per time (10 edits per 10 seconds, as of this writing, although I might have changed that by the time you read this).
The edit limit is by IP address, so two people sharing a router might share an edit limit.
To erase a note, click the white X or press 0, then left-click the main pane.
All users see the same song, with a slight delay. While the song is actively playing, you don’t see edits by other users until it stops.

To save a snapshot of the current song data to your local disk, click EXPORT. A popup will appear with an input box and a hyperlink below it. Type a filename in the input box and the hyperlink will update to that filename. Click the hyperlink to save the snapshot. The snapshot is a self-contained HTML page that does not depend on a server connection and can be opened offline; by design, it only has the playback buttons in its tool subwindow and not the editing ones. Don’t press Enter while editing the filename; due to a minor bug, pressing Enter closes the popup without saving the file.
