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.

Other

Key	Function
`.`	repeat last set value

Numeric columns accept any number that is valid for the given command, using the radix (number base) set in (settings 'number-base). Trigger commands accept any of the piano keys.

REPL

Bindings for the REPL are not finalized yet.

Key	Function
`Return`	Evaluate command

`Ctrl l`	Clear REPL

`Alt p`	Get previous command from history
`Alt n`	Get next command from history

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.

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

Key	Function
`Alt w`	Report value under cursor (what?)
`Alt Shift w`	Report location of cursor (where?)
