Can I add hidden keywords to the keymaps picker?

[lobneroO]

I was just searching for a key binding with the builtin keymaps picker, but couldn't find it. I was searching for "EOL", where the description had "End of line".
Is there a way for me to manually add a hidden keyword for the search? I.e., in my description it is better to have the "End of line" for clarity, but I want "EOL" to point to this as well without cluttering the output like "End of line (EOL)".
