Undo in Media lab

does medialab has the Undo option?

Hm. This question is a tad too brief. What are you trying to undo?

Assuming this is in reference to the Experiment Editor, as of v2008, there is currently no undo feature. If you have a undesired change the only recourse at this point is to close the file without saving the changes. An undo feature is on our [I]to[/I]-do list though for the next version.
