Trint allows you to add and remove markers to certain points in your transcription. Meaning you are able to tag points of interest with ease.
Adding a marker using the toolbar
To add a marker from the toolbar simply highlight the area of text you wish to mark and click the Marker button.

This will place a small blue marker in the wave bar highlighting that this is an area of interest.

Adding and removing a marker using your mouse
To add a marker directly to the wave bar you'll need to right-click on the area of interest and select 'Add a marker'.
If you would like to remove a marker from the wave bar just right-click on the desired marker and select 'Delete marker'
