I found this of interest. Although I still haven't found what I am looking for...and that is a delete key for mac...the backspace/delete key doesn't seem to work for me. I think I have seen an alternative in the past but ...well I'm old ya know...can't remember where!! LOL

I don't tend to use the short cut keys, only really use delete, copy and Paste, I just can't remember the other although I'm sure if I forced myself to use them I would eventually.

Anyways Thanks for the list, I'll have to give it a browse and see how I get on.
