Editing, undo and the lock

Edits and live controls

Two kinds of action happen in the app:

• Edits change the show: patching, groups, layout, tracks, clips, lanes, effects, scenes and settings. They are saved and can be undone.
• Live controls are for performing: launches, faders, mute and solo, tempo, the grand master and channel testing. They aren't undone.

The edit lock

The lock in the header, and its twin in front of the layout selector at the bottom, starts closed, so a show can be played without changing it by accident. Locked, everything live works, but nothing can be added, deleted, moved or edited, Undo is off and Setup's panels can't be used, though they stay on screen. Layouts marked Edit only, such as Setup, leave the layout selector until you unlock (see Screen layouts).

Click the lock, or press ⌘L (Ctrl+L on Windows and Linux), to unlock. It turns amber. Click it or press the key again to lock. The shortcut works in every layout, including while typing in a field or with the formula editor open.

The lock applies to every window and tablet. It only guards against accidents: one click unlocks it, from any window. The headless server starts unlocked with --unlocked.

Undo and redo

⌘Z and ⇧⌘Z (Ctrl+Z and Ctrl+Y) step through edits. The header has no undo buttons unless you add Undo and redo to it in the layout editor. Playing and queued clips follow their scene rows through undo and redo; removing a row stops them.

Quick repeats of the same edit, such as typing a formula or dragging fixtures, undo as one step.

Selecting and changing several things

Click a track's name, a scene's name or a clip to select it. Shift-click selects a range and ⌘-click adds or removes one. Whatever is selected moves, copies, pastes and deletes together (Delete or Backspace; Esc clears the selection). Each is one undo step.

Numbers

Number fields change by dragging up or right (Shift for fine steps); a click edits the text. Numbers inside formulas drag the same way, in steps of their last decimal place, and the lights follow while you drag.

Read-only shows

A show can be marked read-only in the show menu. It still plays and can be edited live, but nothing is saved, and Reload from file restores it. The demo show is read-only; use Save copy as to start your own show from it. The copy keeps the current tempo, faders, mute, solo and playing clips, and stays writable.

Deleting a show

Point at a show in the show menu's list and click ×, then Delete? to confirm. The show's file goes to the Trash, so you can drag it back to the shows folder if you change your mind. Editing has to be unlocked, the open show can't be deleted (open another first), and a read-only show has to be opened and its Read-only unticked first.
