Note Entry

The main part of the keyboard functions like a two-row piano keyboard, as shown in the image below. Key 1 inserts a rest.

Notes on the lower half will use the current base octave, while the upper row will use the current base octave + 1. Holding Shift while entering a note will modify the note's octave. On the lower piano row, the base octave decreases by 1, on the upper row it increases by one.

In the following image, a number in the top right corner of a key represents the regular octave offset, and a number in the lower right corner represents the shifted octave offset.

Bindings for the REPL are not finalized yet.

There are a number of bindings that are not yet configurable. These are mostly standard shortcuts used by any modern text editor, ie. Shift + arrow keys selects, Ctrl-C/Ctrl-X/Ctrl-V copies/cuts/pastes, and so on.

Screen Reader

These bindings assume you have a screen reader enabled in config.scm.
