I would like an automatic bookmark at the point of last edit for each file being edited and a command/button to goto that point.
Usage: edit, edit, edit.
I want to cut and past some code from a few pages up. Scroll up, cut.
Now I need to get back to my point of last edit.
If I could push a button it would be simple. At the moment I need to scroll down looking for the place that I last edited.
You could try the xretrace macro - see the first and second posts in that thread for usage.

See the comments at the start of xretrace.e for more detail.
Try the command xretrace_modified_line - it will take you back to the last "region" where you modified something - which might be in another file. You can't go back to the last modified place in the current buffer unless that was the last actual modification you did - but xretrace_modified_line_steps will let you step a whole buffer at a time using alt-left and alt-right.
In the example you give - you modify something, go somewhere else and "cut" something, you've now made two modifications. If they're within a few lines of each other (i.e. within the same region), xretrace_modified_line probably doesn't remember the first one - but otherwise, it alternates between the last two regions where you did a modification (I think!). Even if you don't want to track modified lines, you can still use the xretrace_cursor or xretrace_cursor_steps command to re-visit where you've been.
