[chimerax-users] pause/wait read user input in chimerax script

Greetings, I would be grateful for help with a script. I made a .cxc script. Now, I would like to show somebody the steps, one by one as in I download this [return] I select that [return] colour these [return] but I cannot see how to insert a pause/wait or something that waits on keyboard input. I did try to insert a "runscript" and put some lines in a python script that reads from the keyboard, but it looks as if chimerax has redirected the script's stdin. I have a feeling, that if I knew what I was doing, I could put another line in the python script "import chimerax.core" and read until the next newline from the command line. Is there a way to pause after each line in a script ? Many thanks for any advice.
