OK, I love stretch so much that I had to assign a really good shortcut to it. I barely ever use S for symbol - I always go into that tool to find the symbol I want so I find that shortcut pretty useless. I changed it to B (block) as I couldn't seem to leave it blank.
Now, is there a way to assign S to stretch without it forcing the command key? Obviously that is used for save and I don't want that but I cannot seem to give just a letter as a shortcut...
