By default, in which-key, descriptions that are longer than 27 characters are truncated, and .. is added. How can I prevent this eliding and show the beginning and end of a long function name?

There's a customizable variable you can set: which-key-max-description-length

Setting it to nil will prevent it from truncating.

From the describe-variable output:

Documentation:

Truncate the description of keys to this length. Also adds "..". If nil, disable any truncation.

(setq which-key-max-description-length nil)

image of long function name not truncated

  • I was aware of this option. However, it is not what I'm looking for.

    i think if you set it to nil it will not truncate at all, is that what you're looking for?
