Total Ion Current (TIC) chromatograms are displayed in the TIC tab in the Chromatogram Processor. Both the retention time and the intensity axis can be zoomed, by holding down the left mouse button and dragging a rectangle around the region you want to rescale. To unzoom the TIC, press the Zoom Out button in the top right corner.

To select a scan from the TIC, click anywhere in the chromatogram pane and the scan corresponding to the selected retention time will be displayed in the Scan tab. The active scan is indicated by a vertical line, which is purple by default. To move the scan point to the next or previous scan, click one of the two arrow buttons, depending on the direction you want to move the scan point. Retention times (tR) scan numbers and scan filters of active scans are displayed in the status bar.
