1. emacs -Q
2. M-x
3. project-switch-project
4. Select '... (choose a dir)'
5. Navigate to a project directory and press enter
6. You are presented with a dispatch menu showing all the available
options from 'project-switch-commands', but the keys are not displayed
but instead the commands and even if you manually look up the keys
connected to these commands pressing those keys doesn't work as
well. Only thing that I found worked in this menu was 'C-g' to cancel.
I have never used this feature before, so I am not sure what is supposed
to happen, but I saw a screenshot of the feature showing the keys
presented and I presume when I press any one of those keys ('f' for
example) I will be taken to the corresponding command for the project.
