DESCRIPTION

"apropos" searches through the documentation of all currently defined commands and lists those commands for which the keyword is either contained in the documentation or matches the command name itself.

If an appropriate DESCRIPTION section is provided in the documentation of the command, the first 80 characters are listed as a summary.

INSTALLATION

1. copy the script bellow to a folder and name it apropos.py

2. run it from within pymol with the run command:

run apropos.py

3. see example bellow on how to use it

USAGE

apropos [keyword or regexp]

EXAMPLE

apropos fit
