Keyboard shortcuts
Every key Plexora binds, in the viewer and in each tool.
On macOS, ⌘ is Command; on Windows and Linux use Ctrl instead. Single letters work whenever you are not typing in a field. Help › Keyboard Shortcuts (⌘/) lists the menu shortcuts in the app, and each open tool lists its own keys under the ? in its header.
