Copy the rjTimelineMarker folder to your Maya scripts directory:
Add the interface and functionality to Maya:
import maya.cmds as cmds cmds.evalDeferred("import rjTimelineMarker; rjTimelineMarker.install()")
This line of code can also be added in the userSetup.py if you would like the functionality to persist.
The UI elements are added to the timeline menu and can be accessed by right clicking on the timeline. You have the option to change the color of your marker points and also add comments where necessary. ToolTips will appear to show the comment while hovering over the timeline. The markers are stored in the maya file.
The hotkey function can be used to setup hotkeys to manage the timeline markers. There are three options, this is to either add, remove or clear the markers. Make sure the language is set to python.
