Most of the basic editing functions (Copy / Paste / Cut / Delete) work in exactly the same way as in any text editor or image editor. The Delete in All Tracks function works like Delete but extends its action to all the tracks of the document instead of just the currently selected one.
The Paste Over function allows you to literally paste the content of the clipboard over the current sound, effectively mixing it with the document instead of just inserting it at the insertion point.
Another useful feature of Amadeus Pro is that tracks can be shuffled around using drag and drop, by clicking into the shaded grey track header. In particular, they can be moved from one document to another. If the sampling rate and / or sampling depth of the dragged track does not match that of the receiving document, it will be converted accordingly.
The Extend to Crossing function in the Selection menu allows you to extend the current selection to the nearest points where the waveform crosses the 0-line. This is probably best illustrated by the following two screenshots, where the left hand side shows the selection of a sound before applying this function and the right hand side shows the same sound after applying the Extend to Crossing function.
This is very useful in order to avoid little crackling noises at the points where sounds are cut and pasted.
