There are three 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.
Next, you can use the functionality of you laptop trackpad. Using two fingers pinch to zoom in or push to zoom out.
Lastly, you can 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)
