There are two easy ways to zoom in or out of your roadmap.
Zoom in/out of the timeline: You can quickly change the roadmap timeline to be shorter or longer with the Zoom icons in the lower right of the roadmap.
You can also use your browser’s zoom feature to show more Lanes in your browser window. This retains your pre-set time period. On Windows, click Ctrl – or Ctrl + and on a Mac, use Command – or Command +. (Note: Using the browser’s zoom feature might cause some Milestone Poles to disappear)
