Thank you for your post.
Testing, Development and Product Management are aware of Undo is not available in the Script Workspace. I recommend that you enter this suggestion into our Feature Requests web form at:
The entries into this web form populate a database file that is hosted and monitored by Product Management and Development. All entries are discussed and considered for possible implementation in a future release. Although I could copy your post and paste it into the web form, there are a couple of contact questions asked on the form that only you can answer.
I will post there in the future. As a modest user of the forums I am still not up to speed where things are.
Can you direct me where to post a request to change my username for the forum? I was ported over from past memberships but I am not sure which is being used here. But, the forum is currently showing my email address rather than a username for every post I make and that is not a very good idea.
Undo will not work in the Scripting!
