7. Keyboard shortcuts

Nebula is being built keyboard-first (every action will eventually be listed in a rebindable shortcut registry, with a searchable command palette); that is still being built out. What is implemented and working today:

Shortcut	Action
Space	Play / stop
Ctrl+N	New project
Ctrl+S	Save
Ctrl+Z	Undo
Ctrl+Y or Ctrl+Shift+Z	Redo
Ctrl+T	Add track
Ctrl+Shift+T	Add audio track
Ctrl+E	Split the selected clip at the playhead
Ctrl+D	Duplicate the selected clip
Delete	Delete the selected clip
Ctrl+L	Toggle loop
Ctrl+= / Ctrl+-	Zoom the timeline in / out
Ctrl+,	Open Settings
Ctrl+Alt+B	Toggle the browser panel
Ctrl+Alt+D	Toggle the bottom (instrument/log/piano) panel
Ctrl+Q	Quit

Every menu item shows its shortcut next to it, and the help strip at the bottom of the window names the shortcut (where one exists) for whatever you are pointing at.

The computer keyboard as a piano

While the instrument screen's Keys view has focus, the letter row plays notes:

A W S E D F T G Y H U J K

Z and X move the octave down and up. These letter keys are only active while the instrument screen (or a similar note-entry view) has keyboard focus, so they never collide with the shortcuts above, which mostly use Ctrl.

On the Pads view (a drum-style instrument), the same physical keys trigger the pads in order instead of piano notes.

What is still to come

A full, rebindable keymap (Settings > Keys & Shortcuts), a searchable command palette, and context-aware shortcuts for views that do not have one yet (the step grid, the piano roll) are planned but not built yet.
