In version 0.18.0 there is just one working command in the Exercise menu: Run
as exercise. Clicking on it will ‘scramble’ the TextGrids in the currently open
Session. This means that the boundaries get redistributed equidistantly from
each other within the recordings.
After that you can practice aligning the boundaries to which ever data modalities are open.
Please note, that in 0.18.0, saving the TextGrids overwrites the originals. This planned to be changed in 0.18.1 to protect the example answer.
There will be further commands enabled in versions 0.18.1 onwards to enable saving and other functionality. See the Changelog’s Unreleased section for further details.
