How to send text highlighted in Chrome to Google Keep?

Google Keep (Mac and iPhone) is a different kind of notes app which can be quite convenient in specific circumstances, especially to store information found in web pages.
Notes can be color coded, which is useful.
Once in Keep notes can be seen and edited on any device.
I can open Google Keep as a Google app in Chrome (not a Mac app), but I can’t figure out how to transfer information into Google Keep with a KBM macro.
There is no send to Google Keep in the services menu.
thanks very much
