Set Key

set_key binds a Python function or PyMOL command to a key press.

Such key binding customization is typically done with your pymolrc startup script.

Changes with PyMOL version:

  • 1.8: decorator support
  • 1.7: second argument can also be a string in PyMOL command syntax

PyMOL API

cmd.set_key(string key, function fn, tuple arg=(), dict kw={})

Also supported since PyMOL 1.7:

cmd.set_key(string key, string command)

Decorator support since PyMOL 1.8:

cmd.set_key(string key)(function fn)

PyMOL Command (since PyMOL 1.7)

set_key key, command

Examples

from pymol import cmd

# define a custom function which colors a selection blue
def make_it_blue(selection): cmd.color("blue", selection)

# color "object1" blue when the F1 key is pressed
cmd.set_key( 'F1' , make_it_blue, [ "object1" ] )
