Gantt chart - Columns
Columns can be hidden or shown by right-clicking the left area in your schedule or right-clicking the header of the columns:
Start & End date column
The last column in the row is what we call the navigation column. It has no header but when you hover over this column in a particular row that contains a time block or icon, it shows an arrow icon forward or backward which will take you directly to that date in the Gantt chart. Especially for larger projects, this can be really useful to navigate back and forth on the horizontal axis.
