undo/redo stack.
This stack is cleared each time the content of the timeline changes.
If you have built up a complex selection and then accidentally cleared it,
- choosing <kbd class="menu">Edit > Undo Selection Change</kbd> will restore your
- previous selection.
+ choosing <kbd class="menu">Edit > Undo Selection Change</kbd> will restore your previous selection.
If you then decide that you had in fact made the correct change, choosing
<kbd class="menu">Edit > Redo Selection Change</kbd> will take you back
to where you were before you chose <kbd class="menu">Edit > Undo Selection Change</kbd>.
