To mark all immaterial accounts with one tick, follow the steps below:

1. In the Trial Balance screen, single left-mouse click on the current year column heading.

2. Highlight the immaterial accounts by clicking and dragging down the account number column.

3. Ensure the Global Annotation button is selected so that the tickmarks flow to all relevant automatic documents (e.g. Leadsheets), then click the Not Material tickmark on the annotation toolbar. This will add the tickmark to all highlighted accounts.
