When using `@` to mention files, it should default to showing a list of all files rather than 'no matches'

What feature would you like to see?

Currently when we use @ to mention a file, it defaults to showing 'no matches':

▌@
▌no matches

But sometimes I don't remember the name of the file I want to mention straight away, and so need to separately check the folder externally, or prompt with an ls type command or similar.

It would be nice if typing @ defaulted to showing the list of files that I could then select from, rather than the less useful 'no matches'.

A current hacky workaround is to type @ followed by a vowel, and know that at least that way I will see some selection of files that I could pick from, but this feels like a bit of a hack, and there is still a 1 in 5'ish chance I wouldn't see the file I wanted still anyway.

Are you interested in implementing this feature?

Unfortunately I don't have the capacity to currently, nor the familiarity with rust.
