Console panel

Open the console with Ctrl+Shift+C(Win / Linux) or⌘+Shift+C(Mac). Enter JavaScript in the input line and press Enter to evaluate it in the application context. Results appear above the prompt; evaluation errors are shown with ERROR:. The console can inspect and edit the current document, not just calculate values.

var selected = Score.selectedObject();
if (selected) console.log(Score.path(selected));
console.log(Score.documentName());

Completion and history

The prompt offers completion for Score, Util and Device; Ctrl+Space requests completion. Up and Down browse command history, which is saved across application restarts.

Shortcut in the input line	Action
Ctrl+A / Ctrl+E	Move to start / end.
Ctrl+B / Ctrl+F	Move backward / forward one character.
Ctrl+U	Clear the line.
Ctrl+K	Delete from cursor to end.
Ctrl+W	Delete the previous word.
Ctrl+T	Transpose neighboring characters.

Editing safely

Use Score.withMacro(function() { ... }) to group document changes into one undo step; inspect Score.canUndo() and Score.undoText() before undoing. Device writes, filesystem operations and shell commands are not automatically undoable. Console scripts have the application’s permissions: paste only trusted code.

See Scripting for library scripts, startup scripts and menu actions, and the editor scripting reference for Score, Util, View, devices and protocols. The Javascript process uses a separate execution engine, so a console variable is not automatically available in its tick. The JavaScript/QML language overview explains the runtime differences.
