There are only certain attributes that can be bulk edited, unfortunately this does not include interactions.
However the paste action for the widgets is very smart. If they are all identical then the approach I take is as follows (lets presume it's OnClick, which is the most commonly used interaction):
- Choose the first component, edit the OnClick event until it is perfect.
- Right mouse click the OnClick interaction in the properties tab for the component, and choose copy. Alternatively, select the OnClick interaction and use the copy keyboard shortcut (Windows: CtrlC MacOs: Cmd ⌘ C)
- Select on all the components that you wish to apply the OnClick interaction to.
- Use the paste keyboard shortcut (Windows: CtrlV MacOs: Cmd ⌘ V).
This will apply the initial one to all the others.
Clearing them out is a pain, you have to choose each one individually, select the OnClick event and press del.
