# Timeline Editor The `timeline editor` is one of the central parts of Dialogic, allowing you create your dialogue tree using the Events system. This editor consists of two parts: the main area, and the event bar on the side. The event bar allows you to add events to the main area, and the main area is where you write your text and arrange the events to create your timeline tree. ## Building a timeline Begin by pressing an event button or dragging it onto the main area in a desired location. Once in the timeline tree, you can move events by dragging and dropping them. ## Shortcuts By holding CTRL, you can select multiple events by clicking on them. By holding SHIFT, you can select a range of events from the one initially selected to the one you click on. The editor supports the following short-cuts: ` CRTL+C copy selected events CRTL+P paste selected events CRTL+X cut selected events DEL delete selected events DOWN/UP select the next/previous event ALT+UP/DOWN move the selected event up or down (only works with one event) CRTL+A select all events CRTL+SHIFT+A deselect all events CRTL+Z undo the last event action CRTL+Y or CRTL+SHIFT+Z redo the last undone action CRTL+T add a new Text event `
