Look even nerdier in front of your friends ! set internal_prompt,f !
internal_prompt turns the internal 'PyMOL>' prompt on or off. The typed commands are not seen anymore, unless you use the esc toggle, which allows you as usual to see the console dialogue. The last line of verbose is still visible where the command line used to be.
where boolean can be either of true, false, t, f, 1 or 0.
I wish it was possible to replace the usual prompt by any given string, and especially by the current path like it is possible in other consoles.
