Hello Cootaholics
I'd like to add a custom button (or key binding, or both) that will do a simple
mutate, keep the residue type the same, and trim it back to the beta carbon.
This would be the same as the stub function in the Simple Mutate dialogue
box. I am finding that I repeat this action
The function you want is
delete_residue_sidechain()

For keybindings, pythonics (old version), please see (Kill Sidechain):
