Delete Features from Created Layer - Undo?

Discussion created by mjt81 on Jul 18, 2011
Hi there,

I'm a fairly new user of ArcGIS, I???ve created a layer in ArcMap 9.2 by selecting some OS MasterMap features by attribute and creating a new layer with them (off the right click menu). I realised that I had selected some features I didn???t need for the new layer, so I selected them and used the ???delete features??? tool on the new layer. However this appears to have removed them from the entire geodatabase! Any idea if I can undo this? If not, how I do import just these features back into my geodatabase?

Thank you! Matt
