How to map K to show docstrings in pylsp?

[ubaldot]

Pressure of K trigger the command :!python3 - pydoc 'text_under_the_cursor' and I am wondering if it is possible to change such a behavior in such a way that when I hit K a popup/balloon showing the docstring of the word under the cursor is shown.

As described in the help for the :LspHover command, you can use the following setting:

:set keywordprg=:LspHover

With this, if you press K on a keyword, it will invoke the :LspHover command.
