Yes, Org uses it for things that are similar to each other, like the
"Export to HTML" options:

  [h] As a HTML file  [H] As a HTML buffer

And Magit uses it for different log listing styles for instance:

  [l] Short  [L] Long

I didn't have anything specific in mind, just thinking why remove the
possibility if the user wishes to do so? Maybe "e" and "E" could be used
to launch different shells in the project root, for instance:

  [e] Shell  [E] Eshell

Or having string search and regexp search commands separately:

  [s] Find string  [S] Find regexp

Me too. The only gripe I (and Dmitry) had with it was that we preferred
the layout of the current interface. For me it's because I find it hard
to distinguish the bold letters used by read-multiple-choice. Would it
be an option to change read-multiple-choice's prompt to use brackets to
distinguish key choices instead? If more people prefer it, making it the
default, or if not, at least adding it as an option? In that case I
wouldn't hesitate to change project-switch-project to use
read-multiple-choice.
